110 * CryptoConfig.cs: Accept lower/mixed-case algorithm names in
111 CreateFromName and MapNameToOID methods (fix bug #79641). Removed OID
112 mappings in 2.0 for DSA and 3DES (they were part of the betas but not
113 in the final 2.0 release of the framework).

133 * HashAlgorithm.cs: Changed the order of BlockCopy + HashCore to
134 HashCore + BlockCopy. Fx 2.0 now allows using a null output buffer
135 (without exception) while previous 1.x versions crashed the runtime
136 (mono won't crash the runtime, so we always do like 2.0).
138 2006-05-30 Sebastien Pouliot <sebastien@ximian.com>
140 * AsymmetricKeyExchangeDeformatter.cs: Under 2.0 the ctor is

162 2005-12-15 Sebastien Pouliot <sebastien@ximian.com>
164 * SymmetricAlgorithm.cs: Changing (not setting) BlockSize must
165 re-generate a new IV (so the properties are kept valid). Note that
166 changing or setting (same value) the KeySize always re-generate a key.
168 2005-12-01 Sebastien Pouliot <sebastien@ximian.com>
170 * RIPEMD160Managed.cs: Endianess fix.
172 2005-11-22 Sebastien Pouliot <sebastien@ximian.com>
174 * DSAManaged.cs: Don't output J in the XML if it's not exported (i.e.

180 * KeyNumber.cs: Added missing [Serializable] present in 2.0.
182 2005-10-21 Sebastien Pouliot <sebastien@ximian.com>
184 * DESCryptoServiceProvider.cs: Don't change the instance key/iv when
185 creating an encryptor or decryptor specifying them. Generate a new key
186 if null is specified (not really useful but compatible with MS
187 behaviour). Check for weak/semi-weak key when creating transforms.
188 * RC2CryptoServiceProvider.cs: Don't change the instance key/iv when
189 creating an encryptor or decryptor specifying them. Check legal key
190 sizes when creating transforms.
191 * RijndaelManaged.cs: Don't change the instance key/iv when creating
192 an encryptor or decryptor specifying them. Check legal key sizes when
194 * TripleDESCryptoServiceProvider.cs: Don't change the instance key/iv
195 when creating an encryptor or decryptor specifying them. Generate a
196 new key if null is specified (not really useful but compatible with MS
197 behaviour). Check for weak key when creating transforms.
199 2005-09-29 Sebastien Pouliot <sebastien@ximian.com>
201 * HMACSHA1.cs: Added the new 2.0 ctor that let the programmer choose
202 between the managed and unmanaged SHA1 algorithm used in the HMAC
203 (that doesn't change much thing in the default config for Mono).
204 * PasswordDeriveBytes.cs: Added [Obsolete] on GetBytes (2.0) as new
205 applications should be using Rfc2898DeriveBytes to get PKCS#5 v2
208 2005-08-17 Sebastien Pouliot <sebastien@ximian.com>
210 * FromBase64Transform.cs: Check that the TransformFinal can be called
211 with only whitespace (with FromBase64TransformMode.IgnoreWhiteSpaces)
212 so that we must return new byte [0].
214 2005-06-14 Sebastien Pouliot <sebastien@ximian.com>
216 * FromBase64Transform.cs: Removed memory allocations during the
217 transform. It's now just the accumulator (ctor) and the
218 TransformFinalBlock that allocates memory. The transform is now
219 between 3 to 4 times faster than before.
221 2005-06-10 Sebastien Pouliot <sebastien@ximian.com>

280 length is bigger than 2^32 bits.
282 2005-03-03 Sebastien Pouliot <sebastien@ximian.com>
284 * RNGCryptoServiceProvider.cs: Added a new call in the static ctor
285 to check if we're using a global handle. In that case we lock before
288 2005-02-10 Sebastien Pouliot <sebastien@ximian.com>
290 * DSA.cs: Weekly fix to case where DSAParameters.Counter is 0 :-(
291 A new unit test was added for this specific case so it's hopefully

308 * DSACryptoServiceProvider.cs: Import|ExportCspBlob throws
309 NotImplementedException (CryptoConvert class doesn't support DSA yet).
310 * RSACryptoServiceProvider.cs: SignHash/VerifyHash defaults to SHA-1
311 in 2.0. VerifyHash throw appropriate exception when no OID is
312 specified (1.0/1.1). Import|ExportCspBlob implemented using the
314 * RSAOAEPKeyExchangeDeformatter.cs: Throw exception if no key is
316 * RSAOAEPKeyExchangeFormatter.cs: Throw exception if no key is

360 TripleDES to be more efficient by using the permutations itself.
361 * TripleDESCryptoServiceProvider.cs: Removed memory allocation in
362 Transform's ECB method. Changed code to directly call DES's
363 permutations. MACTripleDES is now 20% faster (didn't have any other
364 3DES benchmark on hand) and requires much less memory.
366 2005-01-03 Sebastien Pouliot <sebastien@ximian.com>
368 * DESCryptoServiceProvider.cs: Now using pre-computed tables (instead
369 of using a static constructor to compute them). Not much change
370 performance-wise unless you used DES but only "a little" ;-). The old
371 code (who computed the results) is still present but commented,
373 2005-01-02 Sebastien Pouliot <sebastien@ximian.com>
375 * SHA1CryptoServiceProvider.cs: Removed memory allocation in
376 ProcessBlock method (now global). This gives up to 8% performance
377 increase when multiple blocks are being used.

395 2004-12-06 Sebastien Pouliot <sebastien@ximian.com>
397 * RSACryptoServiceProvider.cs: Adjust DecryptValue to the fact that
398 Mono's RSAManaged support decryption without CRT while MS requires it.

695 2004-02-26 Sebastien Pouliot <sebastien@ximian.com>
697 * DES.cs: Same fix as for SymmetricAlgorithm (get_Key is
698 overridden to check for weak keys). Also ensured that no weak keys
700 * SymmetricAlgorithm.cs: Return a copy of the key (and IV) so it

725 * HashAlgorithm.cs: Changed the ComputeHash(Stream) method to (a) not
726 allocate the whole stream memory (big memory saver as suggested by
727 Peter Williams in bugzilla entry #54022) and (b) to never use Stream.
728 Length and Stream.Position because they aren't implemented for every
729 stream class (similar issue to the CryptoStream patch).
730 * MD5CryptoServiceProvider.cs: Moved a buffer allocation from
731 ProcessBlock to constructor to reduce memory allocation. Optimization
732 suggested by Peter Williams in bugzilla entry #54024.

754 with the class (Read/WriteByte, reading by non-multiple of the
755 block size, using Stream.Length and Stream.Position ...).
756 * SymmetricAlgorithm.cs: Return an empty array when there's nothing
757 to return (required for CryptoStream to work).
759 2004-01-31 David Sheldon <dave-mono@earth.li>

986 2003-02-03 Sebastien Pouliot <spouliot@videotron.ca>
988 * PasswordDeriveBytes.cs: Finally got the derivation right. The
989 class can now derive keys up to 1000 * HashSize (same limit as MS).
990 * RSAPKCS1SignatureDeformatter.cs: No need to create the hash object
991 in this class - the OID is enough.

1047 2003-01-03 Sebastien Pouliot <spouliot@videotron.ca>
1049 * RC2CryptoServiceProvider.cs: Now about 2 time faster by inlining

1067 (no parameter) constructor. Now checks for keypairGenerated in methods.
1068 * SignatureDescription.cs: Added CreateDeformatter in RSAPKCS1SHA1-
1069 SignatureDescription to please corcompare (it just call it's ancestor).
1071 2002-12-30 Sebastien Pouliot <spouliot@videotron.ca>

1150 * DSA.cs: Added internal class DSAHandler (which implements IHandler
1151 interface for MiniParser) to import DSA keypairs from XML strings.
1152 * DSACryptoServiceProvider.cs: Crypto fully implemented using
1153 BigInteger. Key generation (group) is VERY long.
1154 * MiniParser.cs: New. Minimal XML parser by Sergey Chaban. Used to
1155 import keypairs in XML strings.
1156 * SignatureDescription.cs: Removed local CreateFromName (to use
1157 CryptoConfig - which actually can create anything). Added internal
1158 classes DSASignatureDescription and RSAPKCS1SHA1SignatureDescription.
