8 CreateFromName method. This allows the framework to be extensible with
9 new certificate extensions (syntax is missing from machine.config).
11 2006-10-12 Sebastien Pouliot <sebastien@ximian.com>
13 * CryptoConfig.cs: Use SmallXmlParser with a custom handler to reduce
14 memory requirements to process machine.config. Fix #79653 (beagle).
16 2006-10-11 Sebastien Pouliot <sebastien@ximian.com>
18 * CryptoConfig.cs: Accept lower/mixed-case algorithm names in
19 CreateFromName and MapNameToOID methods (fix bug #79641). Removed OID
20 mappings in 2.0 for DSA and 3DES (they were part of the betas but not
21 in the final 2.0 release of the framework).
23 2006-09-20 Kazuki Oikawa <kazuki@panicode.com>
25 * RijndaelManaged.cs: improves the performance.
27 2006-09-08 Sebastien Pouliot <sebastien@ximian.com>

37 the hash instance. Fix for bug #78744 by Diego Mesa Tabares.
39 2006-06-15 Sebastien Pouliot <sebastien@ximian.com>
41 * HashAlgorithm.cs: Changed the order of BlockCopy + HashCore to
42 HashCore + BlockCopy. Fx 2.0 now allows using a null output buffer
43 (without exception) while previous 1.x versions crashed the runtime
44 (mono won't crash the runtime, so we always do like 2.0).
46 2006-05-30 Sebastien Pouliot <sebastien@ximian.com>
48 * AsymmetricKeyExchangeDeformatter.cs: Under 2.0 the ctor is
50 * AsymmetricKeyExchangeFormatter.cs: Under 2.0 the ctor is protected.

70 2005-12-15 Sebastien Pouliot <sebastien@ximian.com>
72 * SymmetricAlgorithm.cs: Changing (not setting) BlockSize must
73 re-generate a new IV (so the properties are kept valid). Note that
74 changing or setting (same value) the KeySize always re-generate a key.
76 2005-12-01 Sebastien Pouliot <sebastien@ximian.com>
78 * RIPEMD160Managed.cs: Endianess fix.
80 2005-11-22 Sebastien Pouliot <sebastien@ximian.com>
82 * DSAManaged.cs: Don't output J in the XML if it's not exported (i.e.
83 if it wasn't imported too but instead calculated from the other
86 2005-11-09 Sebastien Pouliot <sebastien@ximian.com>
88 * KeyNumber.cs: Added missing [Serializable] present in 2.0.
90 2005-10-21 Sebastien Pouliot <sebastien@ximian.com>
92 * DESCryptoServiceProvider.cs: Don't change the instance key/iv when
93 creating an encryptor or decryptor specifying them. Generate a new key
94 if null is specified (not really useful but compatible with MS
95 behaviour). Check for weak/semi-weak key when creating transforms.
96 * RC2CryptoServiceProvider.cs: Don't change the instance key/iv when
97 creating an encryptor or decryptor specifying them. Check legal key
98 sizes when creating transforms.
99 * RijndaelManaged.cs: Don't change the instance key/iv when creating
100 an encryptor or decryptor specifying them. Check legal key sizes when
102 * TripleDESCryptoServiceProvider.cs: Don't change the instance key/iv
103 when creating an encryptor or decryptor specifying them. Generate a
104 new key if null is specified (not really useful but compatible with MS
105 behaviour). Check for weak key when creating transforms.
107 2005-09-29 Sebastien Pouliot <sebastien@ximian.com>
109 * HMACSHA1.cs: Added the new 2.0 ctor that let the programmer choose
110 between the managed and unmanaged SHA1 algorithm used in the HMAC
111 (that doesn't change much thing in the default config for Mono).
112 * PasswordDeriveBytes.cs: Added [Obsolete] on GetBytes (2.0) as new
113 applications should be using Rfc2898DeriveBytes to get PKCS#5 v2
116 2005-08-17 Sebastien Pouliot <sebastien@ximian.com>
118 * FromBase64Transform.cs: Check that the TransformFinal can be called
119 with only whitespace (with FromBase64TransformMode.IgnoreWhiteSpaces)
120 so that we must return new byte [0].
122 2005-06-14 Sebastien Pouliot <sebastien@ximian.com>
124 * FromBase64Transform.cs: Removed memory allocations during the
125 transform. It's now just the accumulator (ctor) and the
126 TransformFinalBlock that allocates memory. The transform is now
127 between 3 to 4 times faster than before.
129 2005-06-10 Sebastien Pouliot <sebastien@ximian.com>
131 * all: 2.0 beta2 fixes, i.e. mostly added [ComVisible(true)]

153 2005-05-16 Sebastien Pouliot <sebastien@ximian.com>
155 * CryptoConfig.cs: Initialization wasn't threadsafe as the "checked"
156 value was assigned at the start of the initialization.
158 2005-04-25 Sebastien Pouliot <sebastien@ximian.com>
160 * CryptoConfig.cs: Removed RSA OID and added null check in EncodeOID

188 length is bigger than 2^32 bits.
190 2005-03-03 Sebastien Pouliot <sebastien@ximian.com>
192 * RNGCryptoServiceProvider.cs: Added a new call in the static ctor
193 to check if we're using a global handle. In that case we lock before
196 2005-02-10 Sebastien Pouliot <sebastien@ximian.com>
198 * DSA.cs: Weekly fix to case where DSAParameters.Counter is 0 :-(
199 A new unit test was added for this specific case so it's hopefully

248 Clear buffers when initializing (e.g. re-using the hash instance).
249 * Rfc2898DeriveBytes.cs: Added a new constructor where the password

271 permutations. MACTripleDES is now 20% faster (didn't have any other
272 3DES benchmark on hand) and requires much less memory.
274 2005-01-03 Sebastien Pouliot <sebastien@ximian.com>
276 * DESCryptoServiceProvider.cs: Now using pre-computed tables (instead
277 of using a static constructor to compute them). Not much change
278 performance-wise unless you used DES but only "a little" ;-). The old
279 code (who computed the results) is still present but commented,
281 2005-01-02 Sebastien Pouliot <sebastien@ximian.com>
283 * SHA1CryptoServiceProvider.cs: Removed memory allocation in

603 2004-02-26 Sebastien Pouliot <sebastien@ximian.com>
605 * DES.cs: Same fix as for SymmetricAlgorithm (get_Key is
606 overridden to check for weak keys). Also ensured that no weak keys
608 * SymmetricAlgorithm.cs: Return a copy of the key (and IV) so it
609 doesn't get destroyed when dispose is called (in this case the key
610 zeroization is the caller's responsability). Match MS implementation.
611 * TripleDES.cs: Same fix as for SymmetricAlgorithm (get_Key is
612 overridden to check for weak keys). Fix bugzilla #54868.
614 2004-02-12 Sebastien Pouliot <sebastien@ximian.com>
616 * CryptoStream.cs: Remove the _blockSize assumptions because some
617 Transforms could be different on Input/Output. Added a special case
618 for cascading CryptoStreams in FlushFinalBlock.
620 2004-02-09 Sebastien Pouliot <sebastien@ximian.com>
622 * DSACryptoServiceProvider.cs: Fixed support for key pair persistence.

624 container. PersistKeyInCsp default value also changes if a
625 CspParameters is supplied (or not) to the constructor.
626 * RSACryptoServiceProvider.cs: Same fixes as DSA.
627 * SymmetricAlgorithm.cs: Reintroduced the patch from 2003-08-24 to fix

629 accident some time ago :(
631 2004-02-08 Sebastien Pouliot <sebastien@ximian.com>
633 * HashAlgorithm.cs: Changed the ComputeHash(Stream) method to (a) not
634 allocate the whole stream memory (big memory saver as suggested by
635 Peter Williams in bugzilla entry #54022) and (b) to never use Stream.
636 Length and Stream.Position because they aren't implemented for every
637 stream class (similar issue to the CryptoStream patch).
638 * MD5CryptoServiceProvider.cs: Moved a buffer allocation from
639 ProcessBlock to constructor to reduce memory allocation. Optimization
640 suggested by Peter Williams in bugzilla entry #54024.
642 2004-02-06 Sebastien Pouliot <sebastien@ximian.com>
644 * DSACryptoServiceProvider.cs: Added keypair persistence support.

651 and moved it to Mono.Security.Cryptography namespace. The transform
652 class will also be included in Mono.Security assembly.
654 2004-02-06 David Sheldon <dave-mono@earth.li>
656 * FromBase64Transform.cs: Improved code layout to match coding style,
657 and removed the Byte comparison with -1.
659 2004-02-04 Sebastien Pouliot <sebastien@ximian.com>
661 * CryptoStream.cs: New implementation - should fix all known issues
662 with the class (Read/WriteByte, reading by non-multiple of the
663 block size, using Stream.Length and Stream.Position ...).
664 * SymmetricAlgorithm.cs: Return an empty array when there's nothing
665 to return (required for CryptoStream to work).
667 2004-01-31 David Sheldon <dave-mono@earth.li>
669 * FromBase64Transform.cs: Removed needless catch and rethrow.
671 2004-01-31 David Sheldon <dave-mono@earth.li>

674 input stream is not in the lookup table. IndexOutOfRangeException was
677 2003-12-15 Sebastien Pouliot <spouliot@videotron.ca>
679 * CryptoConfig.cs: Now use internal Environment.GetMachineConfigPath()
680 to find machine.config. Initialization removed from static constructor
681 to speed up 98% of software that do not requires it.
682 * SymmetricAlgorithm.cs: Fixed padding for None and Zeros modes. Unit
683 tests for padding modes are now in PaddingModeTest.cs.
685 2003-12-10 Zoltan Varga <vargaz@freemail.hu>
687 * HMAC.cs: Fix compilation warnings.
689 2003-12-10 Mark Crichton <crichton@gimp.org>

706 2003-11-10 Sebastien Pouliot <spouliot@videotron.ca>
708 * Rfc2898DeriveBytes.cs: Implementation for PKCS5 PBKDF2. It works
709 except for the Reset() part - which implies some kind of Resume.

753 * CryptoStream.cs: Added [In,Out] attributes to Read method.
755 2003-08-24 Sebastien Pouliot <spouliot@videotron.ca>
757 * SymmetricAlgorithm.cs: Fixed IV length exception for stream ciphers
758 (e.g. RC4) which don't uses IV. This needs more tests for small IV...
760 2003-08-09 Sebastien Pouliot <spouliot@videotron.ca>
762 * SymmetricAlgorithm.cs: Re-introduced Lluis patch for PaddingMode.None
763 and PaddingMode.Zeros (not PaddingMode.PKCS7).

852 * RC2.cs: Modified to use IsLegalKeySize from KeySizes.cs.
853 * RSACryptoServiceProvider.cs: Fix bug where key generation always
854 resulted in 1024 bits keypair. Should fix unit test failure under
856 * SymmetricAlgorithm.cs: Moved IsLegalKeySize to KeySizes.cs.
858 2003-04-06 Sebastien Pouliot <spouliot@videotron.ca>
860 * CryptoStream.cs: Partial fix for bug #40689 (workaround). Does not

862 (like MS does but unlike MS documents).
864 2003-03-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
866 * CryptoStream.cs: fixed the previous fix. MS throws a NotSupportedExc
867 when FlushFinalBlock is called twice. I've moved a few lines from Close
868 to FlushFinalBlock and added the exception check.
870 2003-03-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
872 * CryptoStream.cs: don't Close the underlying stream in FlushFinalBlock.
875 2003-03-03 Sebastien Pouliot <spouliot@videotron.ca>
877 * RSACryptoServiceProvider.cs: Delay keypair generation event when
878 keysize is a constructor parameter (major speed improvment when
879 importing keys). Removed NotSupportedException when CspParameter is
880 used in constructor (required for forthcoming security tools).
882 2003-02-08 Sebastien Pouliot <spouliot@videotron.ca>
884 * Changes to refer Mono.Math and Mono.Security.Cryptography
885 * Changes to refer Mono.Xml
887 2003-02-04 Sebastien Pouliot <spouliot@videotron.ca>
889 * CryptoConfig.cs: Added initital support for "machine.config"
890 (limited to algorithms, not OIDs). Modified CreateFromName to use
891 the fully qualified class names (and removed xmldsig hack). Added
892 algorithm names documented in book ".NET Framework Security".
894 2003-02-03 Sebastien Pouliot <spouliot@videotron.ca>
896 * PasswordDeriveBytes.cs: Finally got the derivation right. The
897 class can now derive keys up to 1000 * HashSize (same limit as MS).
898 * RSAPKCS1SignatureDeformatter.cs: No need to create the hash object
899 in this class - the OID is enough.
901 2003-02-01 Sebastien Pouliot <spouliot@videotron.ca>
903 * AsymmetricSignatureFormatter.cs: Call abstract SetHashAlgorithm
904 when CreateSignature(hash) is called.
905 * CryptoStream.cs: Fixed some issues in constructor.
906 * DSACryptoServiceProvider.cs: Fixed a bug (1 chance in 256) that

909 2003-01-25 Sebastien Pouliot <spouliot@videotron.ca>
911 * CryptographicException.cs: Default HResult to CORSEC_E_CRYPTO
912 (0x80131430) as documented.

926 implementation of block-based algorithms (like MAC and HMAC).
927 * HMACSHA1.cs: Refactored to remove dependencies on CryptoStream,
928 better constructors and Dispose support.
929 * MACTripleDES.cs: Refactored to reuse new HMACSHA1 stuff, better

936 2003-01-12 Sebastien Pouliot <spouliot@videotron.ca>
938 * MACTripleDES.cs: Now working (the problem was with my stream usage
939 which was removed for performance reason).
940 * TripleDES.cs: Fixed key generation (wasn't called and returned
943 2003-01-09 Sebastien Pouliot <spouliot@videotron.ca>
945 * RNGCryptoServiceProvider.cs: Changed methods interacting with
946 the runtime as Internal<MethodName>. This will allow to make the
947 class Windows-compatible by doing a switch at runtime.
949 2003-01-05 Sebastien Pouliot <spouliot@videotron.ca>
951 * CryptoAPITransform.cs: Removed all TODO. This class will not be
952 used by Mono. MS uses it with <algo>CryptoServiceProvider classes
953 to provide a common ICryptoTransform access to CryptoAPI.
955 2003-01-03 Sebastien Pouliot <spouliot@videotron.ca>
957 * RC2CryptoServiceProvider.cs: Now about 2 time faster by inlining
958 methods and changing to UInt16 (instead of UInt32).
960 2003-01-02 Sebastien Pouliot <spouliot@videotron.ca>
962 * RijndaelManaged.cs: Now 7 (encrypt) to 10 (decrypt) times faster
963 by removing allocation inside intensively called methods, using pre-
964 calculated tables instead of Mult_GF methods and inlining most methods.
966 2002-12-31 Sebastien Pouliot <spouliot@videotron.ca>
968 * AsymmetricAlgorithm.cs: Removed ValidKeySize (method only present
969 in SymmetricAlgorithm).
970 * DSA.cs: Change ZeroizePrivateKey from protected to internal.
971 * DSACryptoServiceProvider.cs: Added some case where we need to check
972 for keypairGenerated.
973 * RSA.cs: Change ZeroizePrivateKey from protected to internal.
974 * RSACryptoServiceProvider.cs: Key were never generated with the default
975 (no parameter) constructor. Now checks for keypairGenerated in methods.
976 * SignatureDescription.cs: Added CreateDeformatter in RSAPKCS1SHA1-
977 SignatureDescription to please corcompare (it just call it's ancestor).
979 2002-12-30 Sebastien Pouliot <spouliot@videotron.ca>
981 * CryptoStream.cs: Implemented core. Not sure about many details -
982 but it run the samples now (#30256).
983 * CryptoStreamMode.cs: Added [Serializable] to enum declaration.
984 * SymmetricAlgorithm.cs: Made some changes required for CryptoStream
985 and to match more closely MS implementation. Also added little
986 optimizations in TransformBlock.
988 2002-12-27 Sebastien Pouliot <spouliot@videotron.ca>
990 * CryptoTools.cs: New. Shared classes for cryptography. Now
991 includes a KeyBuilder to generate symmetric keys and IV.

1003 using KeyBuilder (and removed TODO).
1005 2002-11-20 Sebastien Pouliot <spouliot@videotron.ca>
1007 * AsymmetricSignatureDeformatter.cs: Added exception handling in
1008 VerifySignature (moved from RSAPKCS1SignatureDeformatter).
1009 * AsymmetricSignatureFormatter.cs: Added exception handling in
1010 CreateSignature (moved from RSAPKCS1SignatureFormatter).
1011 * CryptoAPITransform.cs: Removed "= false" assignation from a private
1012 member (because this created an unwanted "ghost" constructor) and
1013 modified Dispose declaration.
1014 * HashAlgorithm.cs: Removed destructor. Disposing unmanaged
1015 ressources is the responsability of each class (not an abstract class).
1016 * RSAPKCS1SignatureDeformatter.cs: Removed a VerifySignature method
1017 which was present in the base class AsymmetricSignatureDeformatter.
1018 * RSAPKCS1SignatureFormatter.cs: Removed a CreateSignature method
1019 which was present in the base class AsymmetricSignatureFormatter.
1020 * SHA1Managed.cs: Removed sealed from class declaration. Removed
