RC2:: (11 methods):
__construct()
isValidEngineHelper()
setKeyLength()
getKeyLength()
setKey()
encrypt()
decrypt()
encryptBlock()
decryptBlock()
setupKey()
setupInlineCrypt()
| __construct($mode) X-Ref |
| Default Constructor. param: string $mode |
| isValidEngineHelper($engine) X-Ref |
| Test for engine validity This is mainly just a wrapper to set things up for \phpseclib3\Crypt\Common\SymmetricKey::isValidEngine() param: int $engine return: bool see: \phpseclib3\Crypt\Common\SymmetricKey::__construct() |
| setKeyLength($length) X-Ref |
| Sets the key length. Valid key lengths are 8 to 1024. Calling this function after setting the key has no effect until the next \phpseclib3\Crypt\RC2::setKey() call. param: int $length in bits |
| getKeyLength() X-Ref |
| Returns the current key length return: int |
| setKey($key, $t1 = false) X-Ref |
| Sets the key. Keys can be of any length. RC2, itself, uses 8 to 1024 bit keys (eg. strlen($key) <= 128), however, we only use the first 128 bytes if $key has more then 128 bytes in it, and set $key to a single null byte if it is empty. param: string $key param: int|boolean $t1 optional Effective key length in bits. see: \phpseclib3\Crypt\Common\SymmetricKey::setKey() |
| encrypt($plaintext) X-Ref |
| Encrypts a message. Mostly a wrapper for \phpseclib3\Crypt\Common\SymmetricKey::encrypt, with some additional OpenSSL handling code param: string $plaintext return: string $ciphertext see: self::decrypt() |
| decrypt($ciphertext) X-Ref |
| Decrypts a message. Mostly a wrapper for \phpseclib3\Crypt\Common\SymmetricKey::decrypt, with some additional OpenSSL handling code param: string $ciphertext return: string $plaintext see: self::encrypt() |
| encryptBlock($in) X-Ref |
| Encrypts a block param: string $in return: string see: \phpseclib3\Crypt\Common\SymmetricKey::encryptBlock() see: \phpseclib3\Crypt\Common\SymmetricKey::encrypt() |
| decryptBlock($in) X-Ref |
| Decrypts a block param: string $in return: string see: \phpseclib3\Crypt\Common\SymmetricKey::decryptBlock() see: \phpseclib3\Crypt\Common\SymmetricKey::decrypt() |
| setupKey() X-Ref |
| Creates the key schedule see: \phpseclib3\Crypt\Common\SymmetricKey::setupKey() |
| setupInlineCrypt() X-Ref |
| Setup the performance-optimized function for de/encrypt() see: \phpseclib3\Crypt\Common\SymmetricKey::setupInlineCrypt() |
