3 * RSAManaged.cs: Fix the rare case where the inverse of q modulo p
4 can result in bigint one byte shorter than expected, which could
5 mess up the export/import of the key.
7 2007-05-08 Randolph Chung <tausq@debian.org>
9 * CryptoConvert.cs: Add DSA blob conversion functions.
11 2007-03-05 Sebastien Pouliot <sebastien@ximian.com>
13 * SymmetricTransform.cs: Fix KeepLastBlock to be true for decryption
14 with no padding or zero padding. Part of the fix for #81008.
16 2007-01-08 Sebastien Pouliot <sebastien@ximian.com>
18 * SymmetricTransform.cs: Fix #80439 again. This time we have tests for
19 all ciphers, modes and padding.
21 2007-01-04 Sebastien Pouliot <sebastien@ximian.com>
23 * SymmetricTransform.cs: Fix previous fix (for #80439) as we were now
26 2007-01-03 Sebastien Pouliot <sebastien@ximian.com>
28 * SymmetricTransform.cs: Reduce inputCount if larger than the output
29 data can hold. Fix bug #80439.
31 2006-12-11 Sebastien Pouliot <sebastien@ximian.com>
33 * PKCS8.cs: Normalize the private key X integer, not it's ASN.1
34 container, to 20 bytes.
36 2006-10-04 Sebastien Pouliot <sebastien@ximian.com>
38 * PKCS1.cs: Remove compatibility block where all padding wasn't
39 verified (can't find the original test case for it). Note: the
40 existing implementation wasn't affected by CVE-2006-4339, aka RSA
41 PKCS#1 1.5 signature forgery (but we're stronger without it).
43 2006-09-27 Sebastien Pouliot <sebastien@ximian.com>
45 * RSAManaged.cs: Ensure that the results of Encrypt and Decrypt will
46 always be the same length as the key. If smaller then we left pad the
47 result with 0x00 (same integer, correct length for everyone). Fix bug
48 #79502 where an LDAP/SSL server didn't like the missing byte.
50 2006-09-05 Sebastien Pouliot <sebastien@ximian.com>
52 * RSAManaged.cs: Backport NRE fix from mscorlib.dll.
54 2006-06-15 Sebastien Pouliot <sebastien@ximian.com>

57 algorithms when large buffer where used (with multiple calls to
60 2006-02-28 Sebastien Pouliot <sebastien@ximian.com>
62 * CryptoConvert.cs: Make sure we can import a keypair into our RSA
63 instance (even if the key store isn't available). See bug #77559.
64 * PKCS8.cs: Make sure we can import a keypair into our RSA instance
65 (even if the key store isn't available). See bug #77559.
67 2005-11-23 Sebastien Pouliot <sebastien@ximian.com>
69 * SymmetricTransform.cs: Synched with corlib version (IV behaviour for
70 NET_2_0). Virtualized some methods (like Dispose). Fix bug #76801.
72 2005-05-09 Sebastien Pouliot <sebastien@ximian.com>
74 * KeyPairPersistence.cs: Use PlatformID.Unix under NET_2_0.
75 * PKCS8.cs: In sync with corlib;
77 2005-04-18 Sebastien Pouliot <sebastien@ximian.com>
79 * Null.cs: New "null" symmetric encryption for debugging. This class
80 isn't (and shouldn't be) built by default.
81 * SymmetricTransform.cs: Fixed a division by zero if someone changes
82 the feedback value to 0.
83 * SHA224Managed.cs: Fixed warning about unused private constant.

92 * MD2Managed.cs: Removed memory allocation from the transform method.
93 * MD4Managed.cs: Moved memoty allocation to constructor (from init).
94 * SHA224Managed.cs: Fixed bug #73404 which gaves bad results when the
95 digested data is longer than 2^32 bits.
97 2005-01-11 Sebastien Pouliot <sebastien@ximian.com>
99 * SymmetricTransform.cs: Added support for ANSI X9.23 padding and
100 ISO 10126 padding modes (applies to all symmetric block ciphers).
102 2004-12-22 Sebastien Pouliot <sebastien@ximian.com>
104 * KeyPairPersistence.cs: Commented imperative asserts until it is
105 supported by the runtime.
107 2004-12-06 Sebastien Pouliot <sebastien@ximian.com>
109 * RSAManaged.cs: Implement key blinding for RSA decryption with, or
112 2004-11-23 Sebastien Pouliot <sebastien@ximian.com>
114 * PKCS1.cs: Fix PKCS#1 v1.5 decryption when the ciphertext isn't
115 exactly the same of the public key (which happens sometimes on Fx 1.1
116 probably because it doesn't do the last I2OSP operation to left pad
117 the resulting big integer with zeros).
119 2004-11-10 Sebastien Pouliot <sebastien@ximian.com>
121 * RC4.cs: Fixed RC4 for compatibility with .NET 2.0. The algorithm is
122 OK but the check for IV, unused for stream ciphers, has changed.
124 2004-10-28 Sebastien Pouliot <sebastien@ximian.com>
126 * KeyPairPersistence.cs: Added localization for exceptions messages.
127 Also added more details (type and path) when an exception is thrown.
129 2004-09-29 Sebastien Pouliot <sebastien@ximian.com>
131 * RSAManaged.cs: In synch with corlib. KeySize is now always a
132 multiple of 8 bits. Fix #66929.
134 2004-09-17 Sebastien Pouliot <sebastien@ximian.com>
136 * CryptoConvert.cs: In synch with corlib version. Fixed all level 4
137 compilation warnings.

150 2004-06-23 Sebastien Pouliot <sebastien@ximian.com>
152 * SymmetricTransform.cs: Reduce by one the number of block when
153 decrypting. This operation was in CryptoStream before but is only
154 required for decryption (which CryptoStream can't know).
157 2004-05-27 Sebastien Pouliot <sebastien@ximian.com>
159 * ARC4Managed.cs: Added missing exception handling in TransformBlock
160 and TransformFinalBlock.

172 * CryptoConvert.cs: Added support for truncated, but still valid, RSA
173 private key blob. Fix #57941 (couldn't sign with nunit key).
174 * RSAManaged.cs: Normalized the size of D when not present. This
175 allows us to output a compatible base64 representation of 1024bits 0.
177 2004-04-28 Sebastien Pouliot <sebastien@ximian.com>
179 * SymmetricTransform.cs: Fixed bug when offset > 0 in destination

204 2004-03-23 Sebastien Pouliot <sebastien@ximian.com>
206 * CryptoConvert.cs: Added exception for null and bad parameters.
207 * RSAManaged.cs: CryptographicException thrown when trying to export
208 the private key when only the public key is present (CRT aware).
210 2004-03-22 Sebastien Pouliot <sebastien@ximian.com>
212 * CryptoConvert.cs: Added new methods to convert [From|To]Hex. Added
213 new version of FromCapiPublicKeyBlob with an integer offset.
215 2004-03-10 Sebastien Pouliot <sebastien@ximian.com>
217 * PKCS8.cs: Added EncodeRSA, EncodeDSA and completed GetBytes() so it
218 is now possible to encode PKCS8 files (this is required to encode
221 2004-02-15 Sebastien Pouliot <sebastien@ximian.com>
223 * ARC4Managed.cs: Removed all % 256 (modulo) because typecasting to
224 byte already ensure the result would be correct (as suggested by
225 Technoboy). Now use KeyBuilder to create new keys.
227 2004-02-13 Sebastien Pouliot <sebastien@ximian.com>
229 * DHKeyGeneration.cs: New. Enumuration of possible key generation for
230 Diffie-Hellman. Contributed by Pieter Philippaerts (mentalis.org).

238 2004-02-09 Sebastien Pouliot <sebastien@ximian.com>
240 * PKCS1.cs: New. Copied from corlib. Required for RSAManaged.
241 * RSAManaged.cs: New. Copied from corlib. Required for TLS - some
242 parts (MD5SHA1) cannot work with the default RSACryptoServiceProvider.
244 2004-02-06 Sebastien Pouliot <sebastien@ximian.com>
246 * CryptoTools.cs: New. Copied from corlib to offer the sames services

251 services to symmetric algorithms in Mono.Security assembly.
253 2004-01-12 Sebastien Pouliot <spouliot@videotron.ca>
255 * CryptoConvert.cs: RSA doesn't start with a Q - at least that what
256 a strongname told me. Sorry Ron :(
258 2003-11-27 Sebastien Pouliot <spouliot@videotron.ca>
260 * MD4.cs: New. Asbtract class for all MD4 implementations. WARNING:
261 The MD4 algorithm is BROKEN (collisions) and SHOULDN'T be used in
