1 2004-02-09 Sebastien Pouliot <sebastien@ximian.com>
3 * DSACryptoServiceProvider.cs: Fixed support for key pair persistence.
4 It now requires (like MS) to call Clear to delete an existing
5 container. PersistKeyInCsp default value also changes if a
6 CspParameters is supplied (or not) to the constructor.
7 * RSACryptoServiceProvider.cs: Same fixes as DSA.
9 2004-02-08 Sebastien Pouliot <sebastien@ximian.com>
11 * HashAlgorithm.cs: Changed the ComputeHash(Stream) method to (a) not
12 allocate the whole stream memory (big memory saver as suggested by
13 Peter Williams in bugzilla entry #54022) and (b) to never use Stream.
14 Length and Stream.Position because they aren't implemented for every
15 stream class (similar issue to the CryptoStream patch).
16 * MD5CryptoServiceProvider.cs: Moved a buffer allocation from
17 ProcessBlock to constructor to reduce memory allocation. Optimization
18 suggested by Peter Williams in bugzilla entry #54024.

37 2004-02-04 Sebastien Pouliot <sebastien@ximian.com>
39 * CryptoStream.cs: New implementation - should fix all known issues
40 with the class (Read/WriteByte, reading by non-multiple of the

52 input stream is not in the lookup table. IndexOutOfRangeException was
55 2003-12-15 Sebastien Pouliot <spouliot@videotron.ca>
57 * CryptoConfig.cs: Now use internal Environment.GetMachineConfigPath()
58 to find machine.config. Initialization removed from static constructor
59 to speed up 98% of software that do not requires it.
60 * SymmetricAlgorithm.cs: Fixed padding for None and Zeros modes. Unit
61 tests for padding modes are now in PaddingModeTest.cs.
63 2003-12-10 Zoltan Varga <vargaz@freemail.hu>
65 * HMAC.cs: Fix compilation warnings.

133 2003-08-24 Sebastien Pouliot <spouliot@videotron.ca>
135 * SymmetricAlgorithm.cs: Fixed IV length exception for stream ciphers
136 (e.g. RC4) which don't uses IV. This needs more tests for small IV...
138 2003-08-09 Sebastien Pouliot <spouliot@videotron.ca>
140 * SymmetricAlgorithm.cs: Re-introduced Lluis patch for PaddingMode.None
141 and PaddingMode.Zeros (not PaddingMode.PKCS7).

239 throw a NotSupportedException on closing a CryptoStream in read mode
240 (like MS does but unlike MS documents).
242 2003-03-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
244 * CryptoStream.cs: fixed the previous fix. MS throws a NotSupportedExc
245 when FlushFinalBlock is called twice. I've moved a few lines from Close
246 to FlushFinalBlock and added the exception check.
248 2003-03-28 Gonzalo Paniagua Javier <gonzalo@ximian.com>
250 * CryptoStream.cs: don't Close the underlying stream in FlushFinalBlock.
253 2003-03-03 Sebastien Pouliot <spouliot@videotron.ca>
255 * RSACryptoServiceProvider.cs: Delay keypair generation event when
256 keysize is a constructor parameter (major speed improvment when
257 importing keys). Removed NotSupportedException when CspParameter is
258 used in constructor (required for forthcoming security tools).
260 2003-02-08 Sebastien Pouliot <spouliot@videotron.ca>
262 * Changes to refer Mono.Math and Mono.Security.Cryptography
263 * Changes to refer Mono.Xml
265 2003-02-04 Sebastien Pouliot <spouliot@videotron.ca>
267 * CryptoConfig.cs: Added initital support for "machine.config"
268 (limited to algorithms, not OIDs). Modified CreateFromName to use
269 the fully qualified class names (and removed xmldsig hack). Added
270 algorithm names documented in book ".NET Framework Security".
272 2003-02-03 Sebastien Pouliot <spouliot@videotron.ca>
274 * PasswordDeriveBytes.cs: Finally got the derivation right. The
275 class can now derive keys up to 1000 * HashSize (same limit as MS).
276 * RSAPKCS1SignatureDeformatter.cs: No need to create the hash object
277 in this class - the OID is enough.
279 2003-02-01 Sebastien Pouliot <spouliot@videotron.ca>
281 * AsymmetricSignatureFormatter.cs: Call abstract SetHashAlgorithm
282 when CreateSignature(hash) is called.

314 2003-01-12 Sebastien Pouliot <spouliot@videotron.ca>
316 * MACTripleDES.cs: Now working (the problem was with my stream usage
317 which was removed for performance reason).
318 * TripleDES.cs: Fixed key generation (wasn't called and returned
321 2003-01-09 Sebastien Pouliot <spouliot@videotron.ca>
323 * RNGCryptoServiceProvider.cs: Changed methods interacting with
324 the runtime as Internal<MethodName>. This will allow to make the
325 class Windows-compatible by doing a switch at runtime.
327 2003-01-05 Sebastien Pouliot <spouliot@videotron.ca>
329 * CryptoAPITransform.cs: Removed all TODO. This class will not be
330 used by Mono. MS uses it with <algo>CryptoServiceProvider classes
331 to provide a common ICryptoTransform access to CryptoAPI.
333 2003-01-03 Sebastien Pouliot <spouliot@videotron.ca>
335 * RC2CryptoServiceProvider.cs: Now about 2 time faster by inlining
336 methods and changing to UInt16 (instead of UInt32).
338 2003-01-02 Sebastien Pouliot <spouliot@videotron.ca>
340 * RijndaelManaged.cs: Now 7 (encrypt) to 10 (decrypt) times faster
341 by removing allocation inside intensively called methods, using pre-
342 calculated tables instead of Mult_GF methods and inlining most methods.
344 2002-12-31 Sebastien Pouliot <spouliot@videotron.ca>
346 * AsymmetricAlgorithm.cs: Removed ValidKeySize (method only present
347 in SymmetricAlgorithm).

352 * RSACryptoServiceProvider.cs: Key were never generated with the default
353 (no parameter) constructor. Now checks for keypairGenerated in methods.
354 * SignatureDescription.cs: Added CreateDeformatter in RSAPKCS1SHA1-
355 SignatureDescription to please corcompare (it just call it's ancestor).
357 2002-12-30 Sebastien Pouliot <spouliot@videotron.ca>

388 CreateSignature (moved from RSAPKCS1SignatureFormatter).
389 * CryptoAPITransform.cs: Removed "= false" assignation from a private
390 member (because this created an unwanted "ghost" constructor) and
391 modified Dispose declaration.
392 * HashAlgorithm.cs: Removed destructor. Disposing unmanaged
393 ressources is the responsability of each class (not an abstract class).
394 * RSAPKCS1SignatureDeformatter.cs: Removed a VerifySignature method
395 which was present in the base class AsymmetricSignatureDeformatter.
396 * RSAPKCS1SignatureFormatter.cs: Removed a CreateSignature method
397 which was present in the base class AsymmetricSignatureFormatter.

413 of the results as this is not available in all versions of Windows.
414 * RSAOAEPKeyExchangeFormatter.cs: Completed using PKCS1. Not sure
415 of the results as this is not available in all versions of Windows.
416 * RSAPKCS1KeyExchangeDeformatter.cs: Completed using PKCS1.

430 * BigInteger.cs: New. Internal class for handling BIG integers for
431 asymmetric crypto (both RSA and DSA). Thanks to Chew Keong TAN !
432 * CryptoConfig.cs: Added XMLDSIG URLs in CreateFromName.
433 Will dynamically load System.Security.dll, when required,
434 to return instance of those classes. Also CryptoConfig can now
435 create any object (e.g. System.IO.MemoryStream) !
436 * DSA.cs: Added internal class DSAHandler (which implements IHandler
437 interface for MiniParser) to import DSA keypairs from XML strings.
438 * DSACryptoServiceProvider.cs: Crypto fully implemented using
439 BigInteger. Key generation (group) is VERY long.
440 * MiniParser.cs: New. Minimal XML parser by Sergey Chaban. Used to
441 import keypairs in XML strings.
442 * SignatureDescription.cs: Removed local CreateFromName (to use
443 CryptoConfig - which actually can create anything). Added internal
444 classes DSASignatureDescription and RSAPKCS1SHA1SignatureDescription.
446 2002-11-15 Sebastien Pouliot <spouliot@videotron.ca>
