3 * SymmetricTransform.cs: Fix #80439 again. This time we have tests for
4 all ciphers, modes and padding.
6 2007-01-04 Sebastien Pouliot <sebastien@ximian.com>
8 * SymmetricTransform.cs: Fix previous fix (for #80439) as we were now
11 2007-01-03 Sebastien Pouliot <sebastien@ximian.com>
13 * SymmetricTransform.cs: Reduce inputCount if larger than the output
14 data can hold. Fix bug #80439.
16 2006-12-11 Sebastien Pouliot <sebastien@ximian.com>
18 * PKCS8.cs: Normalize the private key X integer, not it's ASN.1
19 container, to 20 bytes.
21 2006-10-04 Sebastien Pouliot <sebastien@ximian.com>
23 * PKCS1.cs: Remove compatibility block where all padding wasn't
24 verified (can't find the original test case for it). Note: the
25 existing implementation wasn't affected by CVE-2006-4339, aka RSA
26 PKCS#1 1.5 signature forgery (but we're stronger without it).
28 2006-09-27 Sebastien Pouliot <sebastien@ximian.com>
30 * RSAManaged.cs: Ensure that the results of Encrypt and Decrypt will
31 always be the same length as the key. If smaller then we left pad the
32 result with 0x00 (same integer, correct length for everyone). Fix bug
33 #79502 where an LDAP/SSL server didn't like the missing byte.
35 2006-09-05 Sebastien Pouliot <sebastien@ximian.com>
37 * RSAManaged.cs: Backport NRE fix from mscorlib.dll.
39 2006-06-15 Sebastien Pouliot <sebastien@ximian.com>

42 algorithms when large buffer where used (with multiple calls to
45 2006-02-28 Sebastien Pouliot <sebastien@ximian.com>
47 * CryptoConvert.cs: Make sure we can import a keypair into our RSA
48 instance (even if the key store isn't available). See bug #77559.
49 * PKCS8.cs: Make sure we can import a keypair into our RSA instance
50 (even if the key store isn't available). See bug #77559.
52 2005-11-23 Sebastien Pouliot <sebastien@ximian.com>
54 * SymmetricTransform.cs: Synched with corlib version (IV behaviour for
55 NET_2_0). Virtualized some methods (like Dispose). Fix bug #76801.
57 2005-05-09 Sebastien Pouliot <sebastien@ximian.com>
59 * KeyPairPersistence.cs: Use PlatformID.Unix under NET_2_0.
60 * PKCS8.cs: In sync with corlib;
62 2005-04-18 Sebastien Pouliot <sebastien@ximian.com>
64 * Null.cs: New "null" symmetric encryption for debugging. This class
65 isn't (and shouldn't be) built by default.
66 * SymmetricTransform.cs: Fixed a division by zero if someone changes
67 the feedback value to 0.
68 * SHA224Managed.cs: Fixed warning about unused private constant.
70 2005-03-30 Sebastien Pouliot <sebastien@ximian.com>
72 * SymmetricTransform.cs: Fixed a padding bug affecting that can occurs
73 when no padding is used.
75 2005-03-07 Sebastien Pouliot <sebastien@ximian.com>
77 * MD2Managed.cs: Removed memory allocation from the transform method.
78 * MD4Managed.cs: Moved memoty allocation to constructor (from init).
79 * SHA224Managed.cs: Fixed bug #73404 which gaves bad results when the
80 digested data is longer than 2^32 bits.
82 2005-01-11 Sebastien Pouliot <sebastien@ximian.com>
84 * SymmetricTransform.cs: Added support for ANSI X9.23 padding and
85 ISO 10126 padding modes (applies to all symmetric block ciphers).
87 2004-12-22 Sebastien Pouliot <sebastien@ximian.com>
89 * KeyPairPersistence.cs: Commented imperative asserts until it is
90 supported by the runtime.
92 2004-12-06 Sebastien Pouliot <sebastien@ximian.com>
94 * RSAManaged.cs: Implement key blinding for RSA decryption with, or
97 2004-11-23 Sebastien Pouliot <sebastien@ximian.com>
99 * PKCS1.cs: Fix PKCS#1 v1.5 decryption when the ciphertext isn't
100 exactly the same of the public key (which happens sometimes on Fx 1.1
101 probably because it doesn't do the last I2OSP operation to left pad
102 the resulting big integer with zeros).
104 2004-11-10 Sebastien Pouliot <sebastien@ximian.com>
106 * RC4.cs: Fixed RC4 for compatibility with .NET 2.0. The algorithm is
107 OK but the check for IV, unused for stream ciphers, has changed.
109 2004-10-28 Sebastien Pouliot <sebastien@ximian.com>
111 * KeyPairPersistence.cs: Added localization for exceptions messages.
112 Also added more details (type and path) when an exception is thrown.
114 2004-09-29 Sebastien Pouliot <sebastien@ximian.com>
116 * RSAManaged.cs: In synch with corlib. KeySize is now always a
117 multiple of 8 bits. Fix #66929.
119 2004-09-17 Sebastien Pouliot <sebastien@ximian.com>
121 * CryptoConvert.cs: In synch with corlib version. Fixed all level 4
122 compilation warnings.
123 * KeyPairPersistence.cs: In synch with corlib version. Fixed all level
124 4 compilation warnings.
125 * PKCS1.cs: In synch with corlib version. Fixed all level 4
126 compilation warnings.

135 2004-06-23 Sebastien Pouliot <sebastien@ximian.com>
137 * SymmetricTransform.cs: Reduce by one the number of block when
138 decrypting. This operation was in CryptoStream before but is only
139 required for decryption (which CryptoStream can't know).
142 2004-05-27 Sebastien Pouliot <sebastien@ximian.com>
144 * ARC4Managed.cs: Added missing exception handling in TransformBlock
145 and TransformFinalBlock.

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

186 * CryptoConvert.cs: Synched with corlib version to get endian fixes
189 2004-03-23 Sebastien Pouliot <sebastien@ximian.com>
191 * CryptoConvert.cs: Added exception for null and bad parameters.
192 * RSAManaged.cs: CryptographicException thrown when trying to export
193 the private key when only the public key is present (CRT aware).
195 2004-03-22 Sebastien Pouliot <sebastien@ximian.com>
197 * CryptoConvert.cs: Added new methods to convert [From|To]Hex. Added
198 new version of FromCapiPublicKeyBlob with an integer offset.
200 2004-03-10 Sebastien Pouliot <sebastien@ximian.com>
202 * PKCS8.cs: Added EncodeRSA, EncodeDSA and completed GetBytes() so it
203 is now possible to encode PKCS8 files (this is required to encode
206 2004-02-15 Sebastien Pouliot <sebastien@ximian.com>
208 * ARC4Managed.cs: Removed all % 256 (modulo) because typecasting to
209 byte already ensure the result would be correct (as suggested by
210 Technoboy). Now use KeyBuilder to create new keys.
212 2004-02-13 Sebastien Pouliot <sebastien@ximian.com>
214 * DHKeyGeneration.cs: New. Enumuration of possible key generation for
215 Diffie-Hellman. Contributed by Pieter Philippaerts (mentalis.org).
216 * DHParameters.cs: New. Structure to hold the different elements of a
217 Diffie-Hellman key. Contributed by Pieter Philippaerts (mentalis.org).

223 2004-02-09 Sebastien Pouliot <sebastien@ximian.com>
225 * PKCS1.cs: New. Copied from corlib. Required for RSAManaged.
226 * RSAManaged.cs: New. Copied from corlib. Required for TLS - some
227 parts (MD5SHA1) cannot work with the default RSACryptoServiceProvider.
229 2004-02-06 Sebastien Pouliot <sebastien@ximian.com>
231 * CryptoTools.cs: New. Copied from corlib to offer the sames services
232 to symmetric algorithms in Mono.Security assembly.

236 services to symmetric algorithms in Mono.Security assembly.
238 2004-01-12 Sebastien Pouliot <spouliot@videotron.ca>
240 * CryptoConvert.cs: RSA doesn't start with a Q - at least that what
241 a strongname told me. Sorry Ron :(
243 2003-11-27 Sebastien Pouliot <spouliot@videotron.ca>
245 * MD4.cs: New. Asbtract class for all MD4 implementations. WARNING:
246 The MD4 algorithm is BROKEN (collisions) and SHOULDN'T be used in
247 NEW designs. However some higher level algorithms (like NTLM) requires
