3 * SymmetricTransform.cs: Fix KeepLastBlock to be true for decryption
4 with no padding or zero padding. Part of the fix for #81008.
6 2007-01-08 Sebastien Pouliot <sebastien@ximian.com>
8 * SymmetricTransform.cs: Fix #80439 again. This time we have tests for
9 all ciphers, modes and padding.
11 2007-01-04 Sebastien Pouliot <sebastien@ximian.com>
13 * SymmetricTransform.cs: Fix previous fix (for #80439) as we were now
16 2007-01-03 Sebastien Pouliot <sebastien@ximian.com>
18 * SymmetricTransform.cs: Reduce inputCount if larger than the output
19 data can hold. Fix bug #80439.
21 2006-12-11 Sebastien Pouliot <sebastien@ximian.com>
23 * PKCS8.cs: Normalize the private key X integer, not it's ASN.1
24 container, to 20 bytes.
26 2006-10-04 Sebastien Pouliot <sebastien@ximian.com>
28 * PKCS1.cs: Remove compatibility block where all padding wasn't
29 verified (can't find the original test case for it). Note: the
30 existing implementation wasn't affected by CVE-2006-4339, aka RSA
31 PKCS#1 1.5 signature forgery (but we're stronger without it).
33 2006-09-27 Sebastien Pouliot <sebastien@ximian.com>
35 * RSAManaged.cs: Ensure that the results of Encrypt and Decrypt will
36 always be the same length as the key. If smaller then we left pad the
37 result with 0x00 (same integer, correct length for everyone). Fix bug
38 #79502 where an LDAP/SSL server didn't like the missing byte.
40 2006-09-05 Sebastien Pouliot <sebastien@ximian.com>
42 * RSAManaged.cs: Backport NRE fix from mscorlib.dll.
44 2006-06-15 Sebastien Pouliot <sebastien@ximian.com>

47 algorithms when large buffer where used (with multiple calls to
50 2006-02-28 Sebastien Pouliot <sebastien@ximian.com>
52 * CryptoConvert.cs: Make sure we can import a keypair into our RSA
53 instance (even if the key store isn't available). See bug #77559.
54 * PKCS8.cs: Make sure we can import a keypair into our RSA instance
55 (even if the key store isn't available). See bug #77559.
57 2005-11-23 Sebastien Pouliot <sebastien@ximian.com>
59 * SymmetricTransform.cs: Synched with corlib version (IV behaviour for
60 NET_2_0). Virtualized some methods (like Dispose). Fix bug #76801.
62 2005-05-09 Sebastien Pouliot <sebastien@ximian.com>
64 * KeyPairPersistence.cs: Use PlatformID.Unix under NET_2_0.
65 * PKCS8.cs: In sync with corlib;
67 2005-04-18 Sebastien Pouliot <sebastien@ximian.com>
69 * Null.cs: New "null" symmetric encryption for debugging. This class
70 isn't (and shouldn't be) built by default.
71 * SymmetricTransform.cs: Fixed a division by zero if someone changes
72 the feedback value to 0.
73 * SHA224Managed.cs: Fixed warning about unused private constant.
75 2005-03-30 Sebastien Pouliot <sebastien@ximian.com>
77 * SymmetricTransform.cs: Fixed a padding bug affecting that can occurs
78 when no padding is used.
80 2005-03-07 Sebastien Pouliot <sebastien@ximian.com>
82 * MD2Managed.cs: Removed memory allocation from the transform method.
83 * MD4Managed.cs: Moved memoty allocation to constructor (from init).
84 * SHA224Managed.cs: Fixed bug #73404 which gaves bad results when the
85 digested data is longer than 2^32 bits.
87 2005-01-11 Sebastien Pouliot <sebastien@ximian.com>
89 * SymmetricTransform.cs: Added support for ANSI X9.23 padding and
90 ISO 10126 padding modes (applies to all symmetric block ciphers).
92 2004-12-22 Sebastien Pouliot <sebastien@ximian.com>
94 * KeyPairPersistence.cs: Commented imperative asserts until it is
95 supported by the runtime.
97 2004-12-06 Sebastien Pouliot <sebastien@ximian.com>
99 * RSAManaged.cs: Implement key blinding for RSA decryption with, or
102 2004-11-23 Sebastien Pouliot <sebastien@ximian.com>
104 * PKCS1.cs: Fix PKCS#1 v1.5 decryption when the ciphertext isn't
105 exactly the same of the public key (which happens sometimes on Fx 1.1
106 probably because it doesn't do the last I2OSP operation to left pad
107 the resulting big integer with zeros).
109 2004-11-10 Sebastien Pouliot <sebastien@ximian.com>
111 * RC4.cs: Fixed RC4 for compatibility with .NET 2.0. The algorithm is
112 OK but the check for IV, unused for stream ciphers, has changed.
114 2004-10-28 Sebastien Pouliot <sebastien@ximian.com>
116 * KeyPairPersistence.cs: Added localization for exceptions messages.
117 Also added more details (type and path) when an exception is thrown.
119 2004-09-29 Sebastien Pouliot <sebastien@ximian.com>
121 * RSAManaged.cs: In synch with corlib. KeySize is now always a
122 multiple of 8 bits. Fix #66929.
124 2004-09-17 Sebastien Pouliot <sebastien@ximian.com>
126 * CryptoConvert.cs: In synch with corlib version. Fixed all level 4
127 compilation warnings.

129 4 compilation warnings.
130 * PKCS1.cs: In synch with corlib version. Fixed all level 4

140 2004-06-23 Sebastien Pouliot <sebastien@ximian.com>
142 * SymmetricTransform.cs: Reduce by one the number of block when
143 decrypting. This operation was in CryptoStream before but is only
144 required for decryption (which CryptoStream can't know).
147 2004-05-27 Sebastien Pouliot <sebastien@ximian.com>
149 * ARC4Managed.cs: Added missing exception handling in TransformBlock
150 and TransformFinalBlock.

162 * CryptoConvert.cs: Added support for truncated, but still valid, RSA
163 private key blob. Fix #57941 (couldn't sign with nunit key).
164 * RSAManaged.cs: Normalized the size of D when not present. This
165 allows us to output a compatible base64 representation of 1024bits 0.
167 2004-04-28 Sebastien Pouliot <sebastien@ximian.com>
169 * SymmetricTransform.cs: Fixed bug when offset > 0 in destination

194 2004-03-23 Sebastien Pouliot <sebastien@ximian.com>
196 * CryptoConvert.cs: Added exception for null and bad parameters.
197 * RSAManaged.cs: CryptographicException thrown when trying to export
198 the private key when only the public key is present (CRT aware).
200 2004-03-22 Sebastien Pouliot <sebastien@ximian.com>
202 * CryptoConvert.cs: Added new methods to convert [From|To]Hex. Added
203 new version of FromCapiPublicKeyBlob with an integer offset.
205 2004-03-10 Sebastien Pouliot <sebastien@ximian.com>
207 * PKCS8.cs: Added EncodeRSA, EncodeDSA and completed GetBytes() so it
208 is now possible to encode PKCS8 files (this is required to encode
211 2004-02-15 Sebastien Pouliot <sebastien@ximian.com>
213 * ARC4Managed.cs: Removed all % 256 (modulo) because typecasting to
214 byte already ensure the result would be correct (as suggested by
215 Technoboy). Now use KeyBuilder to create new keys.
217 2004-02-13 Sebastien Pouliot <sebastien@ximian.com>
219 * DHKeyGeneration.cs: New. Enumuration of possible key generation for
220 Diffie-Hellman. Contributed by Pieter Philippaerts (mentalis.org).

228 2004-02-09 Sebastien Pouliot <sebastien@ximian.com>
230 * PKCS1.cs: New. Copied from corlib. Required for RSAManaged.
231 * RSAManaged.cs: New. Copied from corlib. Required for TLS - some
232 parts (MD5SHA1) cannot work with the default RSACryptoServiceProvider.
234 2004-02-06 Sebastien Pouliot <sebastien@ximian.com>
236 * CryptoTools.cs: New. Copied from corlib to offer the sames services

241 services to symmetric algorithms in Mono.Security assembly.
243 2004-01-12 Sebastien Pouliot <spouliot@videotron.ca>
245 * CryptoConvert.cs: RSA doesn't start with a Q - at least that what
246 a strongname told me. Sorry Ron :(
248 2003-11-27 Sebastien Pouliot <spouliot@videotron.ca>
250 * MD4.cs: New. Asbtract class for all MD4 implementations. WARNING:
251 The MD4 algorithm is BROKEN (collisions) and SHOULDN'T be used in
252 NEW designs. However some higher level algorithms (like NTLM) requires
