3 * PKCS1.cs: Remove compatibility block where all padding wasn't
4 verified (can't find the original test case for it). Note: the
5 existing implementation wasn't affected by CVE-2006-4339, aka RSA
6 PKCS#1 1.5 signature forgery (but we're stronger without it).
8 2006-09-27 Sebastien Pouliot <sebastien@ximian.com>
10 * RSAManaged.cs: Ensure that the results of Encrypt and Decrypt will
11 always be the same length as the key. If smaller then we left pad the
12 result with 0x00 (same integer, correct length for everyone). Fix bug
13 #79502 where an LDAP/SSL server didn't like the missing byte.
15 2006-09-05 Sebastien Pouliot <sebastien@ximian.com>
17 * RSAManaged.cs: Backport NRE fix from mscorlib.dll.
19 2006-06-15 Sebastien Pouliot <sebastien@ximian.com>
21 * CryptoTools.cs: Fix offset in block processor. This fix the HMAC
22 algorithms when large buffer where used (with multiple calls to
25 2006-02-28 Sebastien Pouliot <sebastien@ximian.com>
27 * CryptoConvert.cs: Make sure we can import a keypair into our RSA
28 instance (even if the key store isn't available). See bug #77559.
29 * PKCS8.cs: Make sure we can import a keypair into our RSA instance
30 (even if the key store isn't available). See bug #77559.
32 2005-11-23 Sebastien Pouliot <sebastien@ximian.com>
34 * SymmetricTransform.cs: Synched with corlib version (IV behaviour for
35 NET_2_0). Virtualized some methods (like Dispose). Fix bug #76801.
37 2005-05-09 Sebastien Pouliot <sebastien@ximian.com>
39 * KeyPairPersistence.cs: Use PlatformID.Unix under NET_2_0.
40 * PKCS8.cs: In sync with corlib;
42 2005-04-18 Sebastien Pouliot <sebastien@ximian.com>
44 * Null.cs: New "null" symmetric encryption for debugging. This class
45 isn't (and shouldn't be) built by default.
46 * SymmetricTransform.cs: Fixed a division by zero if someone changes
47 the feedback value to 0.
48 * SHA224Managed.cs: Fixed warning about unused private constant.
50 2005-03-30 Sebastien Pouliot <sebastien@ximian.com>
52 * SymmetricTransform.cs: Fixed a padding bug affecting that can occurs
53 when no padding is used.
55 2005-03-07 Sebastien Pouliot <sebastien@ximian.com>
57 * MD2Managed.cs: Removed memory allocation from the transform method.
58 * MD4Managed.cs: Moved memoty allocation to constructor (from init).
59 * SHA224Managed.cs: Fixed bug #73404 which gaves bad results when the
60 digested data is longer than 2^32 bits.
62 2005-01-11 Sebastien Pouliot <sebastien@ximian.com>
64 * SymmetricTransform.cs: Added support for ANSI X9.23 padding and
65 ISO 10126 padding modes (applies to all symmetric block ciphers).
67 2004-12-22 Sebastien Pouliot <sebastien@ximian.com>
69 * KeyPairPersistence.cs: Commented imperative asserts until it is
70 supported by the runtime.
72 2004-12-06 Sebastien Pouliot <sebastien@ximian.com>
74 * RSAManaged.cs: Implement key blinding for RSA decryption with, or
77 2004-11-23 Sebastien Pouliot <sebastien@ximian.com>
79 * PKCS1.cs: Fix PKCS#1 v1.5 decryption when the ciphertext isn't
80 exactly the same of the public key (which happens sometimes on Fx 1.1
81 probably because it doesn't do the last I2OSP operation to left pad
82 the resulting big integer with zeros).
84 2004-11-10 Sebastien Pouliot <sebastien@ximian.com>
86 * RC4.cs: Fixed RC4 for compatibility with .NET 2.0. The algorithm is
87 OK but the check for IV, unused for stream ciphers, has changed.
89 2004-10-28 Sebastien Pouliot <sebastien@ximian.com>
91 * KeyPairPersistence.cs: Added localization for exceptions messages.
92 Also added more details (type and path) when an exception is thrown.
94 2004-09-29 Sebastien Pouliot <sebastien@ximian.com>
96 * RSAManaged.cs: In synch with corlib. KeySize is now always a
97 multiple of 8 bits. Fix #66929.
99 2004-09-17 Sebastien Pouliot <sebastien@ximian.com>
101 * CryptoConvert.cs: In synch with corlib version. Fixed all level 4
102 compilation warnings.

115 2004-06-23 Sebastien Pouliot <sebastien@ximian.com>
117 * SymmetricTransform.cs: Reduce by one the number of block when
118 decrypting. This operation was in CryptoStream before but is only
119 required for decryption (which CryptoStream can't know).
122 2004-05-27 Sebastien Pouliot <sebastien@ximian.com>
124 * ARC4Managed.cs: Added missing exception handling in TransformBlock
125 and TransformFinalBlock.

137 * CryptoConvert.cs: Added support for truncated, but still valid, RSA
138 private key blob. Fix #57941 (couldn't sign with nunit key).
139 * RSAManaged.cs: Normalized the size of D when not present. This
140 allows us to output a compatible base64 representation of 1024bits 0.
142 2004-04-28 Sebastien Pouliot <sebastien@ximian.com>
144 * SymmetricTransform.cs: Fixed bug when offset > 0 in destination

166 * CryptoConvert.cs: Synched with corlib version to get endian fixes
169 2004-03-23 Sebastien Pouliot <sebastien@ximian.com>
171 * CryptoConvert.cs: Added exception for null and bad parameters.
172 * RSAManaged.cs: CryptographicException thrown when trying to export
173 the private key when only the public key is present (CRT aware).
175 2004-03-22 Sebastien Pouliot <sebastien@ximian.com>
177 * CryptoConvert.cs: Added new methods to convert [From|To]Hex. Added
178 new version of FromCapiPublicKeyBlob with an integer offset.
180 2004-03-10 Sebastien Pouliot <sebastien@ximian.com>
182 * PKCS8.cs: Added EncodeRSA, EncodeDSA and completed GetBytes() so it
183 is now possible to encode PKCS8 files (this is required to encode
186 2004-02-15 Sebastien Pouliot <sebastien@ximian.com>
188 * ARC4Managed.cs: Removed all % 256 (modulo) because typecasting to
189 byte already ensure the result would be correct (as suggested by
190 Technoboy). Now use KeyBuilder to create new keys.
192 2004-02-13 Sebastien Pouliot <sebastien@ximian.com>
194 * DHKeyGeneration.cs: New. Enumuration of possible key generation for
195 Diffie-Hellman. Contributed by Pieter Philippaerts (mentalis.org).

203 2004-02-09 Sebastien Pouliot <sebastien@ximian.com>
205 * PKCS1.cs: New. Copied from corlib. Required for RSAManaged.
206 * RSAManaged.cs: New. Copied from corlib. Required for TLS - some
207 parts (MD5SHA1) cannot work with the default RSACryptoServiceProvider.
209 2004-02-06 Sebastien Pouliot <sebastien@ximian.com>
211 * CryptoTools.cs: New. Copied from corlib to offer the sames services
212 to symmetric algorithms in Mono.Security assembly.

216 services to symmetric algorithms in Mono.Security assembly.
218 2004-01-12 Sebastien Pouliot <spouliot@videotron.ca>
220 * CryptoConvert.cs: RSA doesn't start with a Q - at least that what
221 a strongname told me. Sorry Ron :(
223 2003-11-27 Sebastien Pouliot <spouliot@videotron.ca>
225 * MD4.cs: New. Asbtract class for all MD4 implementations. WARNING:
226 The MD4 algorithm is BROKEN (collisions) and SHOULDN'T be used in
227 NEW designs. However some higher level algorithms (like NTLM) requires
