3 * CryptoConvert.cs: Fix HMAC to respect start index inside an array.
4 Patch by Kazuki Oikawa.
6 2008-03-13 Sebastien Pouliot <sebastien@ximian.com>
8 * CryptoConvert.cs: Re-order exception handling to report the most
9 precise error to caller. Apply RSA extra check to DSA.
10 * RSAManaged.cs: Test imported parameters to ensure the public and
11 private parts of the keypair match together.
13 2008-03-04 Sebastien Pouliot <sebastien@ximian.com>
15 * SymmetricTransform.cs: Fix ANSIX923 padding check (#366623) to be
16 just like PKCS7 (but comparing to 0).
18 2008-02-03 Sebastien Pouliot <sebastien@ximian.com>
20 * DSAManaged.cs: Replace "" (found by Gendarme) with more useful text.
21 * RSAManaged.cs: Replace "" (found by Gendarme) with more useful text.
23 2008-01-10 Sebastien Pouliot <sebastien@ximian.com>
25 * PKCS1.cs: Add a new method that optionally checks for badly
26 padding, technically invalid, PKCS#1 block. This is required to
27 support timestamping verification for Authenticode (since the
28 main timestamping service does this). Fix for #350958
30 2007-11-18 Sebastien Pouliot <sebastien@ximian.com>
32 * RSAManaged.cs: Fix the rare case where the inverse of q modulo p
33 can result in bigint one byte shorter than expected, which could
34 mess up the export/import of the key.
36 2007-05-08 Sebastien Pouliot <sebastien@ximian.com>
38 * CryptoConvert.cs: Sync with Mono.Security version - mostly the patch
39 from Randolph Chung to add DSA CAPI BLOB support.
41 2007-05-08 Randolph Chung <tausq@debian.org>
43 * DSAManaged.cs: Do not reject the input if only Y is null.
44 Fixes #81558. [small edits from Sebastien]
46 2007-03-22 Sebastien Pouliot <sebastien@ximian.com>
48 * SymmetricTransform.cs: Before 2.0 an IndexOutOfRangeException was
49 thrown (for all unmanaged transforms) in case of an overflow.
51 2007-03-05 Sebastien Pouliot <sebastien@ximian.com>
53 * SymmetricTransform.cs: Fix KeepLastBlock to be true for decryption
54 with no padding or zero padding. Part of the fix for #81008.
56 2007-01-08 Sebastien Pouliot <sebastien@ximian.com>
58 * SymmetricTransform.cs: Fix #80439 again. This time we have tests for
59 all ciphers, modes and padding.
61 2007-01-04 Sebastien Pouliot <sebastien@ximian.com>
63 * SymmetricTransform.cs: Fix previous fix (for #80439) as we were now
66 2007-01-03 Sebastien Pouliot <sebastien@ximian.com>
68 * SymmetricTransform.cs: Reduce inputCount if larger than the output
69 data can hold. Fix bug #80439.
71 2006-12-11 Sebastien Pouliot <sebastien@ximian.com>
73 * PKCS8.cs: Synchronize source with Mono.Security.dll
75 2006-09-27 Sebastien Pouliot <sebastien@ximian.com>
77 * RSAManaged.cs: Ensure that the results of Encrypt and Decrypt will
78 always be the same length as the key. If smaller then we left pad the
79 result with 0x00 (same integer, correct length for everyone). Fix bug
80 #79502 where an LDAP/SSL server didn't like the missing byte.
82 2006-09-05 Sebastien Pouliot <sebastien@ximian.com>
84 * RSAManaged.cs: Fix a NRE when decrypting without a private key
85 (#79269). We now throw a CryptographicException with an appropriate
88 2006-06-15 Sebastien Pouliot <sebastien@ximian.com>
90 * CryptoTools.cs: Fix offset in block processor. This fix the HMAC
91 algorithms when large buffer where used (with multiple calls to
94 2005-11-23 Sebastien Pouliot <sebastien@ximian.com>
96 * SymmetricTransform.cs: Virtualized some methods (like Dispose). Fix
99 2005-11-22 Sebastien Pouliot <sebastien@ximian.com>
101 * DSAManaged.cs: Don't export J if it wasn't imported (i.e. it was
102 calculated from the other parameters).
104 2005-10-21 Sebastien Pouliot <sebastien@ximian.com>
106 * SymmetricTransform.cs: Clone IV so it cannot be changed once the
107 transform starts. Generate a new IV if null is specified (not really
108 useful but compatible with MS behaviour). Added a check for IV length
111 2005-05-26 Ben Maurer <bmaurer@ximian.com>
113 * KeyPairPersistence.cs: Lock *before* checking if things are null
114 to prevent race conditions. Also, do not lock on typeof object.
116 2005-05-09 Sebastien Pouliot <sebastien@ximian.com>
118 * KeyPairPersistence.cs: Use PlatformID.Unix under NET_2_0.
120 2005-04-27 Sebastien Pouliot <sebastien@ximian.com>
122 * PKCS8.cs: New. Copied from Mono.Security.dll to allow support of
123 PKCS#12 files in X509Certificate for 2.0.
125 2005-04-18 Sebastien Pouliot <sebastien@ximian.com>
127 * SymmetricTransform.cs: Fixed a division by zero if someone changes
128 the feedback value to 0.
130 2005-03-30 Sebastien Pouliot <sebastien@ximian.com>
132 * SymmetricTransform.cs: Fixed a padding bug affecting that can occurs
133 when no padding is used.
135 2005-01-11 Sebastien Pouliot <sebastien@ximian.com>
137 * DSAManaged.cs: PublicOnly now reports false when a key hasn't yet
139 * RSAManaged.cs: PublicOnly now reports false when a key hasn't yet
142 2005-01-10 Sebastien Pouliot <sebastien@ximian.com>
144 * MACAlgorithm.cs: Added support for different padding modes (required
146 * SymmetricTransform.cs: Added support for ANSI X9.23 padding and
147 ISO 10126 padding modes (applies to all symmetric block ciphers).
149 2004-12-22 Sebastien Pouliot <sebastien@ximian.com>
151 * KeyPairPersistence.cs: Commented imperative asserts until it is
152 supported by the runtime.
154 2004-12-06 Sebastien Pouliot <sebastien@ximian.com>
156 * RSAManaged.cs: Implement key blinding for RSA decryption with, or
159 2004-11-23 Sebastien Pouliot <sebastien@ximian.com>
161 * PKCS1.cs: Fix PKCS#1 v1.5 decryption when the ciphertext isn't
162 exactly the same of the public key (which happens sometimes on Fx 1.1
163 probably because it doesn't do the last I2OSP operation to left pad
164 the resulting big integer with zeros).
166 2004-10-28 Sebastien Pouliot <sebastien@ximian.com>
168 * KeyPairPersistence.cs: Added localization for exceptions messages.
169 Also added more details (type and path) when an exception is thrown.
171 2004-09-29 Sebastien Pouliot <sebastien@ximian.com>
173 * RSAManaged.cs: KeySize is always a multiple of 8 bits (promotion to
174 a bigger size if required) to match MS implementation (and other
177 2004-09-16 Sebastien Pouliot <sebastien@ximian.com>
179 * CryptoConvert.cs: Fixed warning (l4) for unused variables.
180 * KeyPairPersistence.cs: Fixed warning (l4) for unused variable.
181 * PKCS1.cs: Added empty {} to fix warning about possible empty stmnt.
183 2004-07-07 Sebastien Pouliot <sebastien@ximian.com>
185 * MACAlgorithm.cs: Removed the hardcoded PaddingMode.Zeros as this is
186 now selectable in Fx 2.0.
187 * SymmetricTransform.cs: Throw CryptographicException when CipherMode
188 CTS or OFB is being used (to match MS implementation).
190 2004-06-23 Sebastien Pouliot <sebastien@ximian.com>
192 * SymmetricTransform.cs: Reduce by one the number of block when
193 decrypting. This operation was in CryptoStream before but is only
194 required for decryption (which CryptoStream can't know).
197 2004-05-27 Sebastien Pouliot <sebastien@ximian.com>
199 * SymmetricTransform.cs: Fixed possible integer overflow. Added
200 missing exception handling in TransformBlock and TransformFinalBlock.
202 2004-05-01 Sebastien Pouliot <sebastien@ximian.com>
204 * CryptoConvert.cs: Synched with Mono.Security.dll. Fix bug #57941
205 (truncated key pair).
206 * RSAManaged.cs: Synched with Mono.Security.dll. Fix bug #57941
207 (truncated key pair).
209 2004-04-28 Sebastien Pouliot <sebastien@ximian.com>
211 * CryptoConvert.cs: In sync with Mono.Security.dll version.
212 * CryptoTools.cs: In sync with Mono.Security.dll version.
213 * DSAManaged.cs: Changed delegate to please FxCop.
214 * PKCS1.cs: In sync with Mono.Security.dll version.
215 * RSAManaged.cs: In sync with Mono.Security.dll version.
216 * SymmetricTransform.cs: Fixed a bug when offset > 0 in destination
217 buffer. Changed Array.Copy to Buffer.BlockCopy.
219 2004-04-23 Sebastien Pouliot <sebastien@ximian.com>
221 * KeyPairPersistence.cs: Completed key pair protection for both
222 Linux and Windows (protection done by runtime).
224 2004-04-08 Bernie Solomon <bernard@ugsolutions.com>
226 * PKCS1.cs: Use BitConverterLE
228 2004-04-06 Bernie Solomon <bernard@ugsolutions.com>
230 * CryptoConvert.cs: Add private methods to always
231 handle data as little endian (GetBytesLE, ToInt32LE, ToUInt32LE).
233 2004-03-23 Sebastien Pouliot <sebastien@ximian.com>
235 * CryptoConvert.cs: Added support for public keys preceded by an
236 header like the one generated by "sn -e".
238 2004-03-23 Sebastien Pouliot <sebastien@ximian.com>
240 * CryptoConvert.cs: Added exception for null and bad parameters.
241 * RSAManaged.cs: CryptographicException thrown when trying to export
242 the private key when only the public key is present (CRT aware).
244 2004-03-22 Sebastien Pouliot <sebastien@ximian.com>
246 * CryptoConvert.cs: Added new methods to convert [From|To]Hex. Added
247 new version of FromCapiPublicKeyBlob with an integer offset.
249 2004-02-06 Sebastien Pouliot <sebastien@ximian.com>
251 * DSAManaged.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. Added a Random property so
255 we do not always have to create a RNG instance (not always required).
256 * RSAManaged.cs: Added an event after key generation (so that
257 DSACryptoServiceProvider can persist the keypair if required). Added
258 PublicOnly property (like 1.2) so we do not have to catch an exception
259 to know if a private key is present or not.
260 * SymmetricTransform.cs: This class was split from S.S.C.
261 SymmetricAlgorithm.cs so it could be reused in Mono.Security
262 assembly for other symmetric algorithms transforms.
264 2004-02-05 Sebastien Pouliot <sebastien@ximian.com>
266 * KeyPairPersistence.cs: New. Class to persist keypairs in an XML
267 format to mimic the CryptoAPI key containers.
269 2004-01-12 Sebastien Pouliot <spouliot@videotron.ca>
271 * CryptoConvert.cs: RSA doesn't start with a Q - at least that what
272 a strongname told me. Sorry Ron :(
274 2003-12-15 Sebastien Pouliot <spouliot@videotron.ca>
276 * MACAlgorithm.cs: Fixed difference between 1.0 and 1.1 framework.
277 The 1.0 framework is adding an additional padding block (empty)
278 to MAC when MACing an exact multiple of the TripleDES block size.
279 * PKCS1.cs: Fixed a typo which prevented "lame" (without OID)
280 signature verification.
282 2003-10-30 Sebastien Pouliot <spouliot@videotron.ca>
284 * CryptoConvert.cs: Fixed strongname generation for small exponents
285 (like 17). Part of the fixed for bug #50341.
287 2003-10-17 Sebastien Pouliot <spouliot@videotron.ca>
289 * CryptoConvert.cs: Added from Mono.Security to support StrongNames.
291 2003-07-05 Sebastien Pouliot <spouliot@videotron.ca>
293 * DSAManaged.cs: Fixed bugs that appeared with the new unit tests.
294 * RSAManaged.cs: Fixed bugs that appeared with the new unit tests.
296 2003-07-02 Zoltan Varga <vargaz@freemail.hu>
298 * PKCS1.cs DSAManaged.cs: Changed strange characters in comments to
299 human-readable ones, since they break XML export in monocov.
301 2003-06-15 Sebastien Pouliot <spouliot@motus.com>
303 * RSAManaged.cs: Now includes CRT (Chinese Remainder Theorem)
304 optimization when using the private key (DecryptValue). This
305 cut more than 5 seconds of nunit on my system (out of 14 sec
306 for complete asymmetric tests). Thanks to Ben Maurer for help!
308 2003-06-11 Sebastien Pouliot <spouliot@motus.com>
310 * DSAManaged.cs: Refactored from DSACryptoServiceProvider.cs. Cannot
311 be reused outside [ms]corlib because DSA constructor is internal :-(
313 * PKCS1.cs: Now support any hash algorithm when encoding PKCS 1.5
314 (i.e. not limited to pre-calculated values for known hashes). Some
315 other API changes to ease the use of other hash algorithms.
317 * RSAManaged.cs: Refactored from RSACryptoServiceProvider.cs. This
318 class is required for custom PKCS#1 padding in SSL (which is not
319 possible using RSACryptoServiceProvider).
321 2003-05-12 Sebastien Pouliot <spouliot@videotron.ca>
323 * PKCS1.cs: Corrected I2OSP to match PKCS#1 v.2.1 test vector
324 and fix the OAEP incompatibility issue.
326 2003-04-01 Sebastien Pouliot <spouliot@videotron.ca>
328 * PKCS1.cs: Corrected fix (partially) for the lame PKCS1 v1.5
329 signatures done without specifying an OID.
331 2003-03-01 Sebastien Pouliot <spouliot@videotron.ca>
333 * PKCS1.cs: Fix for some (lame) PKCS1 v1.5 signatures done
334 without specifying an OID.
336 2003-02-08 Sebastien Pouliot <spouliot@videotron.ca>
338 * CryptoTools.cs: Renamed namespace to match new location.
339 * PKCS1.cs: Renamed namespace to match new location.
340 * HMACAlgorithm.cs: New. Generic class to implement HMAC
341 using any hash algorithm (was in S.S.C.HMACSHA1.cs).
342 * MACAlgorithm.cs: New. Generic class to implement MAC
343 using any symmetric algorithm (was in S.S.C.MACTripleDES.cs).
