1 2008-03-13 Sebastien Pouliot <sebastien@ximian.com>
3 * CryptoConvert.cs: Re-order exception handling to report the most
4 precise error to caller. Apply RSA extra check to DSA.
5 * RSAManaged.cs: Test imported parameters to ensure the public and
6 private parts of the keypair match together.
8 2008-03-04 Sebastien Pouliot <sebastien@ximian.com>
10 * SymmetricTransform.cs: Fix ANSIX923 padding check (#366623) to be
11 just like PKCS7 (but comparing to 0).
13 2008-02-03 Sebastien Pouliot <sebastien@ximian.com>
15 * DSAManaged.cs: Replace "" (found by Gendarme) with more useful text.
16 * RSAManaged.cs: Replace "" (found by Gendarme) with more useful text.
18 2008-01-10 Sebastien Pouliot <sebastien@ximian.com>
20 * PKCS1.cs: Add a new method that optionally checks for badly
21 padding, technically invalid, PKCS#1 block. This is required to
22 support timestamping verification for Authenticode (since the
23 main timestamping service does this). Fix for #350958
25 2007-11-18 Sebastien Pouliot <sebastien@ximian.com>
27 * RSAManaged.cs: Fix the rare case where the inverse of q modulo p
28 can result in bigint one byte shorter than expected, which could
29 mess up the export/import of the key.
31 2007-05-08 Sebastien Pouliot <sebastien@ximian.com>
33 * CryptoConvert.cs: Sync with Mono.Security version - mostly the patch
34 from Randolph Chung to add DSA CAPI BLOB support.
36 2007-05-08 Randolph Chung <tausq@debian.org>
38 * DSAManaged.cs: Do not reject the input if only Y is null.
39 Fixes #81558. [small edits from Sebastien]
41 2007-03-22 Sebastien Pouliot <sebastien@ximian.com>
43 * SymmetricTransform.cs: Before 2.0 an IndexOutOfRangeException was
44 thrown (for all unmanaged transforms) in case of an overflow.
46 2007-03-05 Sebastien Pouliot <sebastien@ximian.com>
48 * SymmetricTransform.cs: Fix KeepLastBlock to be true for decryption
49 with no padding or zero padding. Part of the fix for #81008.
51 2007-01-08 Sebastien Pouliot <sebastien@ximian.com>
53 * SymmetricTransform.cs: Fix #80439 again. This time we have tests for
54 all ciphers, modes and padding.
56 2007-01-04 Sebastien Pouliot <sebastien@ximian.com>
58 * SymmetricTransform.cs: Fix previous fix (for #80439) as we were now
61 2007-01-03 Sebastien Pouliot <sebastien@ximian.com>
63 * SymmetricTransform.cs: Reduce inputCount if larger than the output
64 data can hold. Fix bug #80439.
66 2006-12-11 Sebastien Pouliot <sebastien@ximian.com>
68 * PKCS8.cs: Synchronize source with Mono.Security.dll
70 2006-09-27 Sebastien Pouliot <sebastien@ximian.com>
72 * RSAManaged.cs: Ensure that the results of Encrypt and Decrypt will
73 always be the same length as the key. If smaller then we left pad the
74 result with 0x00 (same integer, correct length for everyone). Fix bug
75 #79502 where an LDAP/SSL server didn't like the missing byte.
77 2006-09-05 Sebastien Pouliot <sebastien@ximian.com>
79 * RSAManaged.cs: Fix a NRE when decrypting without a private key
80 (#79269). We now throw a CryptographicException with an appropriate
83 2006-06-15 Sebastien Pouliot <sebastien@ximian.com>
85 * CryptoTools.cs: Fix offset in block processor. This fix the HMAC
86 algorithms when large buffer where used (with multiple calls to
89 2005-11-23 Sebastien Pouliot <sebastien@ximian.com>
91 * SymmetricTransform.cs: Virtualized some methods (like Dispose). Fix
94 2005-11-22 Sebastien Pouliot <sebastien@ximian.com>
96 * DSAManaged.cs: Don't export J if it wasn't imported (i.e. it was
97 calculated from the other parameters).
99 2005-10-21 Sebastien Pouliot <sebastien@ximian.com>
101 * SymmetricTransform.cs: Clone IV so it cannot be changed once the
102 transform starts. Generate a new IV if null is specified (not really
103 useful but compatible with MS behaviour). Added a check for IV length
106 2005-05-26 Ben Maurer <bmaurer@ximian.com>
108 * KeyPairPersistence.cs: Lock *before* checking if things are null
109 to prevent race conditions. Also, do not lock on typeof object.
111 2005-05-09 Sebastien Pouliot <sebastien@ximian.com>
113 * KeyPairPersistence.cs: Use PlatformID.Unix under NET_2_0.
115 2005-04-27 Sebastien Pouliot <sebastien@ximian.com>
117 * PKCS8.cs: New. Copied from Mono.Security.dll to allow support of
118 PKCS#12 files in X509Certificate for 2.0.
120 2005-04-18 Sebastien Pouliot <sebastien@ximian.com>
122 * SymmetricTransform.cs: Fixed a division by zero if someone changes
123 the feedback value to 0.
125 2005-03-30 Sebastien Pouliot <sebastien@ximian.com>
127 * SymmetricTransform.cs: Fixed a padding bug affecting that can occurs
128 when no padding is used.
130 2005-01-11 Sebastien Pouliot <sebastien@ximian.com>
132 * DSAManaged.cs: PublicOnly now reports false when a key hasn't yet
134 * RSAManaged.cs: PublicOnly now reports false when a key hasn't yet
137 2005-01-10 Sebastien Pouliot <sebastien@ximian.com>
139 * MACAlgorithm.cs: Added support for different padding modes (required
141 * SymmetricTransform.cs: Added support for ANSI X9.23 padding and
142 ISO 10126 padding modes (applies to all symmetric block ciphers).
144 2004-12-22 Sebastien Pouliot <sebastien@ximian.com>
146 * KeyPairPersistence.cs: Commented imperative asserts until it is
147 supported by the runtime.
149 2004-12-06 Sebastien Pouliot <sebastien@ximian.com>
151 * RSAManaged.cs: Implement key blinding for RSA decryption with, or
154 2004-11-23 Sebastien Pouliot <sebastien@ximian.com>
156 * PKCS1.cs: Fix PKCS#1 v1.5 decryption when the ciphertext isn't
157 exactly the same of the public key (which happens sometimes on Fx 1.1
158 probably because it doesn't do the last I2OSP operation to left pad
159 the resulting big integer with zeros).
161 2004-10-28 Sebastien Pouliot <sebastien@ximian.com>
163 * KeyPairPersistence.cs: Added localization for exceptions messages.
164 Also added more details (type and path) when an exception is thrown.
166 2004-09-29 Sebastien Pouliot <sebastien@ximian.com>
168 * RSAManaged.cs: KeySize is always a multiple of 8 bits (promotion to
169 a bigger size if required) to match MS implementation (and other
172 2004-09-16 Sebastien Pouliot <sebastien@ximian.com>
174 * CryptoConvert.cs: Fixed warning (l4) for unused variables.
175 * KeyPairPersistence.cs: Fixed warning (l4) for unused variable.
176 * PKCS1.cs: Added empty {} to fix warning about possible empty stmnt.
178 2004-07-07 Sebastien Pouliot <sebastien@ximian.com>
180 * MACAlgorithm.cs: Removed the hardcoded PaddingMode.Zeros as this is
181 now selectable in Fx 2.0.
182 * SymmetricTransform.cs: Throw CryptographicException when CipherMode
183 CTS or OFB is being used (to match MS implementation).
185 2004-06-23 Sebastien Pouliot <sebastien@ximian.com>
187 * SymmetricTransform.cs: Reduce by one the number of block when
188 decrypting. This operation was in CryptoStream before but is only
189 required for decryption (which CryptoStream can't know).
192 2004-05-27 Sebastien Pouliot <sebastien@ximian.com>
194 * SymmetricTransform.cs: Fixed possible integer overflow. Added
195 missing exception handling in TransformBlock and TransformFinalBlock.
197 2004-05-01 Sebastien Pouliot <sebastien@ximian.com>
199 * CryptoConvert.cs: Synched with Mono.Security.dll. Fix bug #57941
200 (truncated key pair).
201 * RSAManaged.cs: Synched with Mono.Security.dll. Fix bug #57941
202 (truncated key pair).
204 2004-04-28 Sebastien Pouliot <sebastien@ximian.com>
206 * CryptoConvert.cs: In sync with Mono.Security.dll version.
207 * CryptoTools.cs: In sync with Mono.Security.dll version.
208 * DSAManaged.cs: Changed delegate to please FxCop.
209 * PKCS1.cs: In sync with Mono.Security.dll version.
210 * RSAManaged.cs: In sync with Mono.Security.dll version.
211 * SymmetricTransform.cs: Fixed a bug when offset > 0 in destination
212 buffer. Changed Array.Copy to Buffer.BlockCopy.
214 2004-04-23 Sebastien Pouliot <sebastien@ximian.com>
216 * KeyPairPersistence.cs: Completed key pair protection for both
217 Linux and Windows (protection done by runtime).
219 2004-04-08 Bernie Solomon <bernard@ugsolutions.com>
221 * PKCS1.cs: Use BitConverterLE
223 2004-04-06 Bernie Solomon <bernard@ugsolutions.com>
225 * CryptoConvert.cs: Add private methods to always
226 handle data as little endian (GetBytesLE, ToInt32LE, ToUInt32LE).
228 2004-03-23 Sebastien Pouliot <sebastien@ximian.com>
230 * CryptoConvert.cs: Added support for public keys preceded by an
231 header like the one generated by "sn -e".
233 2004-03-23 Sebastien Pouliot <sebastien@ximian.com>
235 * CryptoConvert.cs: Added exception for null and bad parameters.
236 * RSAManaged.cs: CryptographicException thrown when trying to export
237 the private key when only the public key is present (CRT aware).
239 2004-03-22 Sebastien Pouliot <sebastien@ximian.com>
241 * CryptoConvert.cs: Added new methods to convert [From|To]Hex. Added
242 new version of FromCapiPublicKeyBlob with an integer offset.
244 2004-02-06 Sebastien Pouliot <sebastien@ximian.com>
246 * DSAManaged.cs: Added an event after key generation (so that
247 DSACryptoServiceProvider can persist the keypair if required). Added
248 PublicOnly property (like 1.2) so we do not have to catch an exception
249 to know if a private key is present or not. Added a Random property so
250 we do not always have to create a RNG instance (not always required).
251 * RSAManaged.cs: Added an event after key generation (so that
252 DSACryptoServiceProvider can persist the keypair if required). Added
253 PublicOnly property (like 1.2) so we do not have to catch an exception
254 to know if a private key is present or not.
255 * SymmetricTransform.cs: This class was split from S.S.C.
256 SymmetricAlgorithm.cs so it could be reused in Mono.Security
257 assembly for other symmetric algorithms transforms.
259 2004-02-05 Sebastien Pouliot <sebastien@ximian.com>
261 * KeyPairPersistence.cs: New. Class to persist keypairs in an XML
262 format to mimic the CryptoAPI key containers.
264 2004-01-12 Sebastien Pouliot <spouliot@videotron.ca>
266 * CryptoConvert.cs: RSA doesn't start with a Q - at least that what
267 a strongname told me. Sorry Ron :(
269 2003-12-15 Sebastien Pouliot <spouliot@videotron.ca>
271 * MACAlgorithm.cs: Fixed difference between 1.0 and 1.1 framework.
272 The 1.0 framework is adding an additional padding block (empty)
273 to MAC when MACing an exact multiple of the TripleDES block size.
274 * PKCS1.cs: Fixed a typo which prevented "lame" (without OID)
275 signature verification.
277 2003-10-30 Sebastien Pouliot <spouliot@videotron.ca>
279 * CryptoConvert.cs: Fixed strongname generation for small exponents
280 (like 17). Part of the fixed for bug #50341.
282 2003-10-17 Sebastien Pouliot <spouliot@videotron.ca>
284 * CryptoConvert.cs: Added from Mono.Security to support StrongNames.
286 2003-07-05 Sebastien Pouliot <spouliot@videotron.ca>
288 * DSAManaged.cs: Fixed bugs that appeared with the new unit tests.
289 * RSAManaged.cs: Fixed bugs that appeared with the new unit tests.
291 2003-07-02 Zoltan Varga <vargaz@freemail.hu>
293 * PKCS1.cs DSAManaged.cs: Changed strange characters in comments to
294 human-readable ones, since they break XML export in monocov.
296 2003-06-15 Sebastien Pouliot <spouliot@motus.com>
298 * RSAManaged.cs: Now includes CRT (Chinese Remainder Theorem)
299 optimization when using the private key (DecryptValue). This
300 cut more than 5 seconds of nunit on my system (out of 14 sec
301 for complete asymmetric tests). Thanks to Ben Maurer for help!
303 2003-06-11 Sebastien Pouliot <spouliot@motus.com>
305 * DSAManaged.cs: Refactored from DSACryptoServiceProvider.cs. Cannot
306 be reused outside [ms]corlib because DSA constructor is internal :-(
308 * PKCS1.cs: Now support any hash algorithm when encoding PKCS 1.5
309 (i.e. not limited to pre-calculated values for known hashes). Some
310 other API changes to ease the use of other hash algorithms.
312 * RSAManaged.cs: Refactored from RSACryptoServiceProvider.cs. This
313 class is required for custom PKCS#1 padding in SSL (which is not
314 possible using RSACryptoServiceProvider).
316 2003-05-12 Sebastien Pouliot <spouliot@videotron.ca>
318 * PKCS1.cs: Corrected I2OSP to match PKCS#1 v.2.1 test vector
319 and fix the OAEP incompatibility issue.
321 2003-04-01 Sebastien Pouliot <spouliot@videotron.ca>
323 * PKCS1.cs: Corrected fix (partially) for the lame PKCS1 v1.5
324 signatures done without specifying an OID.
326 2003-03-01 Sebastien Pouliot <spouliot@videotron.ca>
328 * PKCS1.cs: Fix for some (lame) PKCS1 v1.5 signatures done
329 without specifying an OID.
331 2003-02-08 Sebastien Pouliot <spouliot@videotron.ca>
333 * CryptoTools.cs: Renamed namespace to match new location.
334 * PKCS1.cs: Renamed namespace to match new location.
335 * HMACAlgorithm.cs: New. Generic class to implement HMAC
336 using any hash algorithm (was in S.S.C.HMACSHA1.cs).
337 * MACAlgorithm.cs: New. Generic class to implement MAC
338 using any symmetric algorithm (was in S.S.C.MACTripleDES.cs).
