43 2004-04-25 Andreas Nahr <ClassDevelopment@A-SoftTech.com>
45 * DSACryptoServiceProvider.cs: Call invariant compare
47 2004-04-08 Bernie Solomon <bernard@ugsolutions.com>

65 2004-03-09 Atsushi Enomoto <atsushi@ximian.com>
67 * DSA.cs : In ToXmlString(), sequence of Seed and PgenCounter is
70 2004-02-26 Sebastien Pouliot <sebastien@ximian.com>
72 * DES.cs: Same fix as for SymmetricAlgorithm (get_Key is
73 overridden to check for weak keys). Also ensured that no weak keys
75 * SymmetricAlgorithm.cs: Return a copy of the key (and IV) so it
76 doesn't get destroyed when dispose is called (in this case the key
77 zeroization is the caller's responsability). Match MS implementation.
78 * TripleDES.cs: Same fix as for SymmetricAlgorithm (get_Key is
79 overridden to check for weak keys). Fix bugzilla #54868.
81 2004-02-12 Sebastien Pouliot <sebastien@ximian.com>
83 * CryptoStream.cs: Remove the _blockSize assumptions because some
84 Transforms could be different on Input/Output. Added a special case
85 for cascading CryptoStreams in FlushFinalBlock.
87 2004-02-09 Sebastien Pouliot <sebastien@ximian.com>
89 * DSACryptoServiceProvider.cs: Fixed support for key pair persistence.
90 It now requires (like MS) to call Clear to delete an existing
91 container. PersistKeyInCsp default value also changes if a
92 CspParameters is supplied (or not) to the constructor.
93 * RSACryptoServiceProvider.cs: Same fixes as DSA.
94 * SymmetricAlgorithm.cs: Reintroduced the patch from 2003-08-24 to fix
95 IV length exception for stream ciphers (e.g. RC4). I overwrote it by
96 accident some time ago :(
98 2004-02-08 Sebastien Pouliot <sebastien@ximian.com>
100 * HashAlgorithm.cs: Changed the ComputeHash(Stream) method to (a) not
101 allocate the whole stream memory (big memory saver as suggested by
102 Peter Williams in bugzilla entry #54022) and (b) to never use Stream.
103 Length and Stream.Position because they aren't implemented for every
104 stream class (similar issue to the CryptoStream patch).
105 * MD5CryptoServiceProvider.cs: Moved a buffer allocation from
106 ProcessBlock to constructor to reduce memory allocation. Optimization
107 suggested by Peter Williams in bugzilla entry #54024.
109 2004-02-06 Sebastien Pouliot <sebastien@ximian.com>
111 * DSACryptoServiceProvider.cs: Added keypair persistence support.

113 PublicOnly property (as internal before 1.2, public after).
114 * RSACryptoServiceProvider.cs: Added keypair persistence support.
115 Corrected dispose so object cannot be disposed multiple time. Added
116 PublicOnly property (as internal before 1.2, public after).

118 and moved it to Mono.Security.Cryptography namespace. The transform
119 class will also be included in Mono.Security assembly.
121 2004-02-06 David Sheldon <dave-mono@earth.li>
123 * FromBase64Transform.cs: Improved code layout to match coding style,
124 and removed the Byte comparison with -1.
126 2004-02-04 Sebastien Pouliot <sebastien@ximian.com>
128 * CryptoStream.cs: New implementation - should fix all known issues
129 with the class (Read/WriteByte, reading by non-multiple of the
130 block size, using Stream.Length and Stream.Position ...).
131 * SymmetricAlgorithm.cs: Return an empty array when there's nothing
132 to return (required for CryptoStream to work).
134 2004-01-31 David Sheldon <dave-mono@earth.li>
136 * FromBase64Transform.cs: Removed needless catch and rethrow.
138 2004-01-31 David Sheldon <dave-mono@earth.li>
140 * FromBase64Transform.cs: Fixes to what happens if a character in the
141 input stream is not in the lookup table. IndexOutOfRangeException was
144 2003-12-15 Sebastien Pouliot <spouliot@videotron.ca>
146 * CryptoConfig.cs: Now use internal Environment.GetMachineConfigPath()
147 to find machine.config. Initialization removed from static constructor
148 to speed up 98% of software that do not requires it.
149 * SymmetricAlgorithm.cs: Fixed padding for None and Zeros modes. Unit
150 tests for padding modes are now in PaddingModeTest.cs.
152 2003-12-10 Zoltan Varga <vargaz@freemail.hu>
154 * HMAC.cs: Fix compilation warnings.
156 2003-12-10 Mark Crichton <crichton@gimp.org>

164 * ProtectedMemory.cs: Added exceptions - core is still TODO.
166 2003-11-11 Sebastien Pouliot <spouliot@videotron.ca>
168 * Rfc2898DeriveBytes.cs: Now handle resets and keys longer than 160
169 bits (HMACSHA1 block size). Removed TODO.

173 2003-11-10 Sebastien Pouliot <spouliot@videotron.ca>
175 * Rfc2898DeriveBytes.cs: Implementation for PKCS5 PBKDF2. It works
176 except for the Reset() part - which implies some kind of Resume.

206 algorithm from Pieter Philippaerts (Pieter@mentalis.org)
208 2003-10-07 Sebastien Pouliot <spouliot@videotron.ca>
210 * CryptoStream.cs: Commented CanTransformMultipleBlocks
211 optimization - it simply doesn't work :(
213 2003-10-04 Sebastien Pouliot <spouliot@videotron.ca>
215 * CryptoStream.cs: Fixed bug 49323. The CanTransformMultipleBlocks
216 optimization in Read has been fixed for partial blocks.

220 * CryptoStream.cs: Added [In,Out] attributes to Read method.
222 2003-08-24 Sebastien Pouliot <spouliot@videotron.ca>
224 * SymmetricAlgorithm.cs: Fixed IV length exception for stream ciphers
225 (e.g. RC4) which don't uses IV. This needs more tests for small IV...
227 2003-08-09 Sebastien Pouliot <spouliot@videotron.ca>
229 * SymmetricAlgorithm.cs: Re-introduced Lluis patch for PaddingMode.None
230 and PaddingMode.Zeros (not PaddingMode.PKCS7).

319 * RC2.cs: Modified to use IsLegalKeySize from KeySizes.cs.
320 * RSACryptoServiceProvider.cs: Fix bug where key generation always
321 resulted in 1024 bits keypair. Should fix unit test failure under
323 * SymmetricAlgorithm.cs: Moved IsLegalKeySize to KeySizes.cs.
325 2003-04-06 Sebastien Pouliot <spouliot@videotron.ca>
327 * CryptoStream.cs: Partial fix for bug #40689 (workaround). Does not

329 (like MS does but unlike MS documents).
331 2003-03-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
333 * CryptoStream.cs: fixed the previous fix. MS throws a NotSupportedExc
334 when FlushFinalBlock is called twice. I've moved a few lines from Close
335 to FlushFinalBlock and added the exception check.
337 2003-03-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
339 * CryptoStream.cs: don't Close the underlying stream in FlushFinalBlock.
342 2003-03-03 Sebastien Pouliot <spouliot@videotron.ca>
344 * RSACryptoServiceProvider.cs: Delay keypair generation event when
345 keysize is a constructor parameter (major speed improvment when
346 importing keys). Removed NotSupportedException when CspParameter is
347 used in constructor (required for forthcoming security tools).
349 2003-02-08 Sebastien Pouliot <spouliot@videotron.ca>
351 * Changes to refer Mono.Math and Mono.Security.Cryptography
352 * Changes to refer Mono.Xml
354 2003-02-04 Sebastien Pouliot <spouliot@videotron.ca>
356 * CryptoConfig.cs: Added initital support for "machine.config"
357 (limited to algorithms, not OIDs). Modified CreateFromName to use
358 the fully qualified class names (and removed xmldsig hack). Added
359 algorithm names documented in book ".NET Framework Security".
361 2003-02-03 Sebastien Pouliot <spouliot@videotron.ca>
363 * PasswordDeriveBytes.cs: Finally got the derivation right. The
364 class can now derive keys up to 1000 * HashSize (same limit as MS).
365 * RSAPKCS1SignatureDeformatter.cs: No need to create the hash object
366 in this class - the OID is enough.
368 2003-02-01 Sebastien Pouliot <spouliot@videotron.ca>
370 * AsymmetricSignatureFormatter.cs: Call abstract SetHashAlgorithm
371 when CreateSignature(hash) is called.
372 * CryptoStream.cs: Fixed some issues in constructor.
373 * DSACryptoServiceProvider.cs: Fixed a bug (1 chance in 256) that
374 a signature could be less than 40 bytes (which is invalid).
376 2003-01-25 Sebastien Pouliot <spouliot@videotron.ca>
378 * CryptographicException.cs: Default HResult to CORSEC_E_CRYPTO
379 (0x80131430) as documented.

393 implementation of block-based algorithms (like MAC and HMAC).
394 * HMACSHA1.cs: Refactored to remove dependencies on CryptoStream,
395 better constructors and Dispose support.
396 * MACTripleDES.cs: Refactored to reuse new HMACSHA1 stuff, better
399 2003-01-18 Sebastien Pouliot <spouliot@videotron.ca>

403 2003-01-12 Sebastien Pouliot <spouliot@videotron.ca>
405 * MACTripleDES.cs: Now working (the problem was with my stream usage
406 which was removed for performance reason).
407 * TripleDES.cs: Fixed key generation (wasn't called and returned
410 2003-01-09 Sebastien Pouliot <spouliot@videotron.ca>
412 * RNGCryptoServiceProvider.cs: Changed methods interacting with
413 the runtime as Internal<MethodName>. This will allow to make the
414 class Windows-compatible by doing a switch at runtime.
416 2003-01-05 Sebastien Pouliot <spouliot@videotron.ca>
418 * CryptoAPITransform.cs: Removed all TODO. This class will not be
419 used by Mono. MS uses it with <algo>CryptoServiceProvider classes
420 to provide a common ICryptoTransform access to CryptoAPI.
422 2003-01-03 Sebastien Pouliot <spouliot@videotron.ca>
424 * RC2CryptoServiceProvider.cs: Now about 2 time faster by inlining
425 methods and changing to UInt16 (instead of UInt32).
427 2003-01-02 Sebastien Pouliot <spouliot@videotron.ca>
429 * RijndaelManaged.cs: Now 7 (encrypt) to 10 (decrypt) times faster
430 by removing allocation inside intensively called methods, using pre-
431 calculated tables instead of Mult_GF methods and inlining most methods.
433 2002-12-31 Sebastien Pouliot <spouliot@videotron.ca>
435 * AsymmetricAlgorithm.cs: Removed ValidKeySize (method only present
436 in SymmetricAlgorithm).

438 * DSACryptoServiceProvider.cs: Added some case where we need to check
439 for keypairGenerated.
440 * RSA.cs: Change ZeroizePrivateKey from protected to internal.
441 * RSACryptoServiceProvider.cs: Key were never generated with the default
442 (no parameter) constructor. Now checks for keypairGenerated in methods.
443 * SignatureDescription.cs: Added CreateDeformatter in RSAPKCS1SHA1-
444 SignatureDescription to please corcompare (it just call it's ancestor).
446 2002-12-30 Sebastien Pouliot <spouliot@videotron.ca>
448 * CryptoStream.cs: Implemented core. Not sure about many details -
449 but it run the samples now (#30256).
450 * CryptoStreamMode.cs: Added [Serializable] to enum declaration.
451 * SymmetricAlgorithm.cs: Made some changes required for CryptoStream
452 and to match more closely MS implementation. Also added little
453 optimizations in TransformBlock.
455 2002-12-27 Sebastien Pouliot <spouliot@videotron.ca>
457 * CryptoTools.cs: New. Shared classes for cryptography. Now

474 * AsymmetricSignatureDeformatter.cs: Added exception handling in
475 VerifySignature (moved from RSAPKCS1SignatureDeformatter).
476 * AsymmetricSignatureFormatter.cs: Added exception handling in
477 CreateSignature (moved from RSAPKCS1SignatureFormatter).
478 * CryptoAPITransform.cs: Removed "= false" assignation from a private
479 member (because this created an unwanted "ghost" constructor) and
480 modified Dispose declaration.
481 * HashAlgorithm.cs: Removed destructor. Disposing unmanaged
482 ressources is the responsability of each class (not an abstract class).
483 * RSAPKCS1SignatureDeformatter.cs: Removed a VerifySignature method
484 which was present in the base class AsymmetricSignatureDeformatter.
485 * RSAPKCS1SignatureFormatter.cs: Removed a CreateSignature method
486 which was present in the base class AsymmetricSignatureFormatter.
487 * SHA1Managed.cs: Removed sealed from class declaration. Removed
488 destructor and Dispose method as class is fully managed.
489 * ToBase64Transform.cs: Added virtual to property CanReuseTransform.
491 2002-11-17 Sebastien Pouliot <spouliot@videotron.ca>
493 * CryptoConfig.cs: Added full classes name for MapNameToOID.
494 * PKCS1.cs: New. Internal class for the various primitives defined
496 * PKCS1MaskGenerationFunction.cs: Modified to use PKCS1.cs.
497 * RSA.cs: Added internal class RSAHandler (which implements IHandler
498 interface for MiniParser) to import RSA keypairs from XML strings.
499 * RSACryptoServiceProvider.cs: Crypto implemented using BigInteger.
500 Key generation is VERY LONG.
501 * RSAOAEPKeyExchangeDeformatter.cs: Completed using PKCS1. Not sure
502 of the results as this is not available in all versions of Windows.
503 * RSAOAEPKeyExchangeFormatter.cs: Completed using PKCS1. Not sure
504 of the results as this is not available in all versions of Windows.
505 * RSAPKCS1KeyExchangeDeformatter.cs: Completed using PKCS1.
