2014-05-09 phpCrypt-0.5.1 Ryan Gilfether
|
|
|
|
* Fixed error message in Rijndael.php which inaccurately
|
|
reported an incorrect key size in bits instead of bytes
|
|
|
|
* Fixed a typo in the blockSize() call in the Rijdael.php
|
|
contructor
|
|
|
|
2013-09-18 phpCrypt-0.5 Ryan Gilfether
|
|
|
|
* Added CAST-128 cipher
|
|
|
|
* Added CAST-256 cipher
|
|
|
|
* Added support for 8 and 16 byte keys in addition
|
|
to 24 byte keys for Triple DES (3DES)
|
|
|
|
* Removed the OneTimePad cipher. This was redundant since
|
|
the SimpleXOR cipher is the same as a one time pad when
|
|
the key length is the same as the length of data length,
|
|
and the key is unique for each block of data.
|
|
|
|
* Added PHP_Crypt::createKey(), a helper function to generate
|
|
a random string of bytes that can be used as a key for a
|
|
cipher. See the examples directory to see how it is used.
|
|
|
|
* Added PHP_Crypt::setKey() so that it is possible to set
|
|
the key to a new value without having to create an new
|
|
instance of phpCrypt
|
|
|
|
* Renamed PHP_Crypt::cipherSetKey() to PHP_Crypt::cipherKey()
|
|
|
|
* Updated the constants used for PHP_Crypt::createKey() and
|
|
PHP_Crypt::createIV(). Both now use the PHP_Crypt::RAND
|
|
constants. The PHP_Crypt::IV constants have been removed.
|
|
|
|
* Changed SimpleXOR from a block cipher to a stream cipher
|
|
since this is what it really is.
|
|
|
|
* In Cipher.php made the $key member private, renamed
|
|
setKey() to key(), and key() is now used to retrieve the
|
|
current key in use by all extending classes
|
|
|
|
* Minor changes to how RC2::splitBytes() works using
|
|
array_map()
|
|
|
|
* Fixed an error message that occurs in php 5.3 in RC2.php
|
|
|
|
* Renamed Base.php to Core.php
|
|
|
|
* Replaced for() loops with array_map() in Core.php where
|
|
possible for minor speed improvements
|
|
|
|
* Shortened the name of functions in Core.php, and updated
|
|
all files that use those functions.
|
|
|
|
* Create a workaround in Core::rotateBitsLeft32() and
|
|
Core::rotateBitsRight32() which caused them to not always
|
|
work correctly on 32 bit platforms
|
|
|
|
* Fixed Core::uInt() and Core::uInt32() which caused them to
|
|
not always work correctly on 32 bit platforms
|
|
|
|
* Major bug fix in how CTR mode works. Previously it was not
|
|
fully compatible with mCrypt's CTR mode.
|
|
|
|
2013-07-21 phpCrypt-0.4 Ryan Gilfether
|
|
|
|
* Added the 3-Way cipher. phpCrypt's implementation is
|
|
compatible with mCrypts implementation, though there may
|
|
be a bug in mCrypt's 3-Way gamma() function. phpCrypt
|
|
mimics the bug to make it compatible, if it is a bug.
|
|
Unfortunately I do no know enough about 3-Way nor could
|
|
I find much information on it to know if the gamma() function
|
|
is suppose to behave the way it does. Please read phpCrypt's
|
|
3Way::gamma() function comment for further information.
|
|
|
|
* Windows users now have the option to create an IV using
|
|
the secure random number generator found in the Microsoft
|
|
CAPICOM SDK. The new constant is PHP_Crypt::IV_WIN_COM.
|
|
View the README file for more information.
|
|
|
|
* Fixed a bug in CTR mode where the last few bytes may
|
|
not get passed to the cipher in some cases
|
|
|
|
* Mode::CreateIV() now hashes the random string of bytes
|
|
before returning it as the IV. This helps in the adding
|
|
additional 'randomness' to the IV
|
|
|
|
* Bug fixes and minor speed improvements in some of the
|
|
modes.
|
|
|
|
* Updated all functions and calculations to handle block
|
|
size in bytes instead of bits. This makes the API less
|
|
confusing and fewer conversions from bits to bytes.
|
|
|
|
2013-07-19 phpCrypt-0.3.2 Ryan Gilfether
|
|
|
|
* Version 0.3.1 contained some incomplete files and bugs
|
|
which were not fixed before the release. This version
|
|
addresses those issues.
|
|
|
|
* Fixes in the examples code
|
|
|
|
* Removed the PHP_Crypt::setIV() function and renamed to
|
|
PHP_Crypt::IV()
|
|
|
|
2013-07-18 phpCrypt-0.3.1 Ryan Gilfether
|
|
|
|
* Found a major bug in the way IV's are used in Encryption
|
|
and Decryption. The $iv parameter has been removed from
|
|
PHP_Crypt::Encrypt() and PHP_Crypt::Decrypt() function, and
|
|
instead the IV should be set with PHP_Crypt::setIV()
|
|
|
|
* Updated the code in the 'examples' directory to reflect
|
|
the changes made to correct the IV bug
|
|
|
|
* Updated README and README.md to reflect the changes made
|
|
for the IV bug
|
|
|
|
2013-07-12 phpCrypt-0.3 Ryan Gilfether
|
|
|
|
* Added the Blowfish Cipher
|
|
|
|
* Updated CryptBase::decimal2Hex() with a parameter to force
|
|
the returned hex to specified byte size
|
|
|
|
* Updated RC2.php to use the uInt() function
|
|
|
|
* Added PHP_Crypt::SetIV() function
|
|
|
|
* Removed the $iv parameter from PHP_Crypt::CreateIV(),
|
|
now to set the IV use the PHP_Crypt::SetIV() function,
|
|
or pass the IV in the encrypt() or decrypt() function
|
|
|
|
* Renamed CryptBase.php to Base.php. Removed it as a parent
|
|
class to all other classes except the Cipher class, as it
|
|
was the only class that really needed it.
|
|
|
|
* General performance improvements
|
|
|
|
2013-06-28 phpCrypt-0.2 Ryan Gilfether
|
|
|
|
* Fixed Enigma so that it works on both 64 and 32 bit platforms
|
|
|
|
* Renamed & fixed the following functions in CryptBase.php
|
|
to use native PHP function calls:
|
|
uInt(), sInt(), uInt32(), sInt32(), uChar(), sChar()
|
|
|
|
2013-06-24 phpCrypt-0.1 Ryan Gilfether
|
|
|
|
