22 new certificate extensions (syntax is missing from machine.config).
24 2006-10-12 Sebastien Pouliot <sebastien@ximian.com>
26 * CryptoConfig.cs: Use SmallXmlParser with a custom handler to reduce
27 memory requirements to process machine.config. Fix #79653 (beagle).
29 2006-10-11 Sebastien Pouliot <sebastien@ximian.com>
31 * CryptoConfig.cs: Accept lower/mixed-case algorithm names in
32 CreateFromName and MapNameToOID methods (fix bug #79641). Removed OID
33 mappings in 2.0 for DSA and 3DES (they were part of the betas but not
34 in the final 2.0 release of the framework).

50 the hash instance. Fix for bug #78744 by Diego Mesa Tabares.
52 2006-06-15 Sebastien Pouliot <sebastien@ximian.com>
54 * HashAlgorithm.cs: Changed the order of BlockCopy + HashCore to
55 HashCore + BlockCopy. Fx 2.0 now allows using a null output buffer
56 (without exception) while previous 1.x versions crashed the runtime
57 (mono won't crash the runtime, so we always do like 2.0).
59 2006-05-30 Sebastien Pouliot <sebastien@ximian.com>

83 2005-12-15 Sebastien Pouliot <sebastien@ximian.com>
85 * SymmetricAlgorithm.cs: Changing (not setting) BlockSize must
86 re-generate a new IV (so the properties are kept valid). Note that
87 changing or setting (same value) the KeySize always re-generate a key.
89 2005-12-01 Sebastien Pouliot <sebastien@ximian.com>
91 * RIPEMD160Managed.cs: Endianess fix.
93 2005-11-22 Sebastien Pouliot <sebastien@ximian.com>
95 * DSAManaged.cs: Don't output J in the XML if it's not exported (i.e.

99 2005-11-09 Sebastien Pouliot <sebastien@ximian.com>
101 * KeyNumber.cs: Added missing [Serializable] present in 2.0.
103 2005-10-21 Sebastien Pouliot <sebastien@ximian.com>
105 * DESCryptoServiceProvider.cs: Don't change the instance key/iv when
106 creating an encryptor or decryptor specifying them. Generate a new key
107 if null is specified (not really useful but compatible with MS
108 behaviour). Check for weak/semi-weak key when creating transforms.
109 * RC2CryptoServiceProvider.cs: Don't change the instance key/iv when
110 creating an encryptor or decryptor specifying them. Check legal key
111 sizes when creating transforms.
112 * RijndaelManaged.cs: Don't change the instance key/iv when creating
113 an encryptor or decryptor specifying them. Check legal key sizes when
115 * TripleDESCryptoServiceProvider.cs: Don't change the instance key/iv
116 when creating an encryptor or decryptor specifying them. Generate a
117 new key if null is specified (not really useful but compatible with MS
118 behaviour). Check for weak key when creating transforms.
120 2005-09-29 Sebastien Pouliot <sebastien@ximian.com>
122 * HMACSHA1.cs: Added the new 2.0 ctor that let the programmer choose
123 between the managed and unmanaged SHA1 algorithm used in the HMAC
124 (that doesn't change much thing in the default config for Mono).
125 * PasswordDeriveBytes.cs: Added [Obsolete] on GetBytes (2.0) as new
126 applications should be using Rfc2898DeriveBytes to get PKCS#5 v2
129 2005-08-17 Sebastien Pouliot <sebastien@ximian.com>
131 * FromBase64Transform.cs: Check that the TransformFinal can be called
132 with only whitespace (with FromBase64TransformMode.IgnoreWhiteSpaces)
133 so that we must return new byte [0].
135 2005-06-14 Sebastien Pouliot <sebastien@ximian.com>
137 * FromBase64Transform.cs: Removed memory allocations during the
138 transform. It's now just the accumulator (ctor) and the
139 TransformFinalBlock that allocates memory. The transform is now
140 between 3 to 4 times faster than before.
142 2005-06-10 Sebastien Pouliot <sebastien@ximian.com>
144 * all: 2.0 beta2 fixes, i.e. mostly added [ComVisible(true)]

201 length is bigger than 2^32 bits.
203 2005-03-03 Sebastien Pouliot <sebastien@ximian.com>
205 * RNGCryptoServiceProvider.cs: Added a new call in the static ctor
206 to check if we're using a global handle. In that case we lock before
209 2005-02-10 Sebastien Pouliot <sebastien@ximian.com>
211 * DSA.cs: Weekly fix to case where DSAParameters.Counter is 0 :-(
212 A new unit test was added for this specific case so it's hopefully

230 NotImplementedException (CryptoConvert class doesn't support DSA yet).
231 * RSACryptoServiceProvider.cs: SignHash/VerifyHash defaults to SHA-1
232 in 2.0. VerifyHash throw appropriate exception when no OID is
233 specified (1.0/1.1). Import|ExportCspBlob implemented using the
235 * RSAOAEPKeyExchangeDeformatter.cs: Throw exception if no key is
237 * RSAOAEPKeyExchangeFormatter.cs: Throw exception if no key is

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

287 2005-01-03 Sebastien Pouliot <sebastien@ximian.com>
289 * DESCryptoServiceProvider.cs: Now using pre-computed tables (instead
290 of using a static constructor to compute them). Not much change
291 performance-wise unless you used DES but only "a little" ;-). The old
292 code (who computed the results) is still present but commented,
294 2005-01-02 Sebastien Pouliot <sebastien@ximian.com>
296 * SHA1CryptoServiceProvider.cs: Removed memory allocation in

616 2004-02-26 Sebastien Pouliot <sebastien@ximian.com>
618 * DES.cs: Same fix as for SymmetricAlgorithm (get_Key is
619 overridden to check for weak keys). Also ensured that no weak keys
621 * SymmetricAlgorithm.cs: Return a copy of the key (and IV) so it
622 doesn't get destroyed when dispose is called (in this case the key
623 zeroization is the caller's responsability). Match MS implementation.

627 2004-02-12 Sebastien Pouliot <sebastien@ximian.com>
629 * CryptoStream.cs: Remove the _blockSize assumptions because some
630 Transforms could be different on Input/Output. Added a special case

644 2004-02-08 Sebastien Pouliot <sebastien@ximian.com>
646 * HashAlgorithm.cs: Changed the ComputeHash(Stream) method to (a) not
647 allocate the whole stream memory (big memory saver as suggested by
648 Peter Williams in bugzilla entry #54022) and (b) to never use Stream.
649 Length and Stream.Position because they aren't implemented for every
650 stream class (similar issue to the CryptoStream patch).
651 * MD5CryptoServiceProvider.cs: Moved a buffer allocation from
652 ProcessBlock to constructor to reduce memory allocation. Optimization
653 suggested by Peter Williams in bugzilla entry #54024.

675 with the class (Read/WriteByte, reading by non-multiple of the
676 block size, using Stream.Length and Stream.Position ...).
677 * SymmetricAlgorithm.cs: Return an empty array when there's nothing
678 to return (required for CryptoStream to work).
680 2004-01-31 David Sheldon <dave-mono@earth.li>

687 input stream is not in the lookup table. IndexOutOfRangeException was
690 2003-12-15 Sebastien Pouliot <spouliot@videotron.ca>
692 * CryptoConfig.cs: Now use internal Environment.GetMachineConfigPath()
693 to find machine.config. Initialization removed from static constructor
694 to speed up 98% of software that do not requires it.
695 * SymmetricAlgorithm.cs: Fixed padding for None and Zeros modes. Unit
696 tests for padding modes are now in PaddingModeTest.cs.
698 2003-12-10 Zoltan Varga <vargaz@freemail.hu>

770 * SymmetricAlgorithm.cs: Fixed IV length exception for stream ciphers
771 (e.g. RC4) which don't uses IV. This needs more tests for small IV...
773 2003-08-09 Sebastien Pouliot <spouliot@videotron.ca>
775 * SymmetricAlgorithm.cs: Re-introduced Lluis patch for PaddingMode.None
776 and PaddingMode.Zeros (not PaddingMode.PKCS7).

875 (like MS does but unlike MS documents).
877 2003-03-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
879 * CryptoStream.cs: fixed the previous fix. MS throws a NotSupportedExc
880 when FlushFinalBlock is called twice. I've moved a few lines from Close

883 2003-03-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
885 * CryptoStream.cs: don't Close the underlying stream in FlushFinalBlock.
888 2003-03-03 Sebastien Pouliot <spouliot@videotron.ca>

891 keysize is a constructor parameter (major speed improvment when
892 importing keys). Removed NotSupportedException when CspParameter is
893 used in constructor (required for forthcoming security tools).

900 2003-02-04 Sebastien Pouliot <spouliot@videotron.ca>
902 * CryptoConfig.cs: Added initital support for "machine.config"
903 (limited to algorithms, not OIDs). Modified CreateFromName to use
904 the fully qualified class names (and removed xmldsig hack). Added
905 algorithm names documented in book ".NET Framework Security".
907 2003-02-03 Sebastien Pouliot <spouliot@videotron.ca>
909 * PasswordDeriveBytes.cs: Finally got the derivation right. The
910 class can now derive keys up to 1000 * HashSize (same limit as MS).
911 * RSAPKCS1SignatureDeformatter.cs: No need to create the hash object
912 in this class - the OID is enough.
914 2003-02-01 Sebastien Pouliot <spouliot@videotron.ca>
916 * AsymmetricSignatureFormatter.cs: Call abstract SetHashAlgorithm
917 when CreateSignature(hash) is called.
918 * CryptoStream.cs: Fixed some issues in constructor.
919 * DSACryptoServiceProvider.cs: Fixed a bug (1 chance in 256) that

949 2003-01-12 Sebastien Pouliot <spouliot@videotron.ca>
951 * MACTripleDES.cs: Now working (the problem was with my stream usage
952 which was removed for performance reason).
953 * TripleDES.cs: Fixed key generation (wasn't called and returned
956 2003-01-09 Sebastien Pouliot <spouliot@videotron.ca>
958 * RNGCryptoServiceProvider.cs: Changed methods interacting with
959 the runtime as Internal<MethodName>. This will allow to make the

962 2003-01-05 Sebastien Pouliot <spouliot@videotron.ca>
964 * CryptoAPITransform.cs: Removed all TODO. This class will not be
965 used by Mono. MS uses it with <algo>CryptoServiceProvider classes
966 to provide a common ICryptoTransform access to CryptoAPI.
968 2003-01-03 Sebastien Pouliot <spouliot@videotron.ca>
970 * RC2CryptoServiceProvider.cs: Now about 2 time faster by inlining
971 methods and changing to UInt16 (instead of UInt32).
973 2003-01-02 Sebastien Pouliot <spouliot@videotron.ca>
975 * RijndaelManaged.cs: Now 7 (encrypt) to 10 (decrypt) times faster
976 by removing allocation inside intensively called methods, using pre-
977 calculated tables instead of Mult_GF methods and inlining most methods.
979 2002-12-31 Sebastien Pouliot <spouliot@videotron.ca>
981 * AsymmetricAlgorithm.cs: Removed ValidKeySize (method only present
982 in SymmetricAlgorithm).

988 (no parameter) constructor. Now checks for keypairGenerated in methods.
989 * SignatureDescription.cs: Added CreateDeformatter in RSAPKCS1SHA1-
990 SignatureDescription to please corcompare (it just call it's ancestor).
992 2002-12-30 Sebastien Pouliot <spouliot@videotron.ca>
994 * CryptoStream.cs: Implemented core. Not sure about many details -
995 but it run the samples now (#30256).
996 * CryptoStreamMode.cs: Added [Serializable] to enum declaration.
997 * SymmetricAlgorithm.cs: Made some changes required for CryptoStream
998 and to match more closely MS implementation. Also added little
999 optimizations in TransformBlock.

1021 VerifySignature (moved from RSAPKCS1SignatureDeformatter).
1022 * AsymmetricSignatureFormatter.cs: Added exception handling in
1023 CreateSignature (moved from RSAPKCS1SignatureFormatter).
1024 * CryptoAPITransform.cs: Removed "= false" assignation from a private
1025 member (because this created an unwanted "ghost" constructor) and
1026 modified Dispose declaration.
1027 * HashAlgorithm.cs: Removed destructor. Disposing unmanaged
1028 ressources is the responsability of each class (not an abstract class).

1030 which was present in the base class AsymmetricSignatureDeformatter.
1031 * RSAPKCS1SignatureFormatter.cs: Removed a CreateSignature method
1032 which was present in the base class AsymmetricSignatureFormatter.

1045 * RSACryptoServiceProvider.cs: Crypto implemented using BigInteger.
1046 Key generation is VERY LONG.
1047 * RSAOAEPKeyExchangeDeformatter.cs: Completed using PKCS1. Not sure
1048 of the results as this is not available in all versions of Windows.

1068 Will dynamically load System.Security.dll, when required,
1069 to return instance of those classes. Also CryptoConfig can now
1070 create any object (e.g. System.IO.MemoryStream) !
1071 * DSA.cs: Added internal class DSAHandler (which implements IHandler
1072 interface for MiniParser) to import DSA keypairs from XML strings.
1073 * DSACryptoServiceProvider.cs: Crypto fully implemented using
1074 BigInteger. Key generation (group) is VERY long.
1075 * MiniParser.cs: New. Minimal XML parser by Sergey Chaban. Used to
1076 import keypairs in XML strings.
1077 * SignatureDescription.cs: Removed local CreateFromName (to use
1078 CryptoConfig - which actually can create anything). Added internal
1079 classes DSASignatureDescription and RSAPKCS1SHA1SignatureDescription.
