Methods summary

`public Crypt_Hash`	# `Crypt_Hash( optional $hash = 'sha1' )` Default Constructor. Default Constructor. Parameters `$hash` `optional` String $hash Returns `Crypt_Hash`
`public`	# `setKey( String $key )` Sets the key for HMACs Sets the key for HMACs Keys can be of any length. Parameters `$key` `String` $key
`public`	# `setHash( String $hash )` Sets the hash function. Sets the hash function. Parameters `$hash` `String` $hash
`public String`	# `hash( String $text )` Compute the HMAC. Compute the HMAC. Parameters `$text` `String` $text Returns `String`
`public Integer`	# `getLength( )` Returns the hash length (in bytes) Returns the hash length (in bytes) Returns `Integer`
`public`	# `_md5( String $m )` Wrapper for MD5 Wrapper for MD5 Parameters `$m` `String` $text
`public`	# `_sha1( String $m )` Wrapper for SHA1 Wrapper for SHA1 Parameters `$m` `String` $text
`public`	# `_md2( String $m )` Pure-PHP implementation of MD2 Pure-PHP implementation of MD2 See RFC1319. Parameters `$m` `String` $text
`public`	# `_sha256( String $m )` Pure-PHP implementation of SHA256 Pure-PHP implementation of SHA256 See SHA-256 (a SHA-2 variant) pseudocode - Wikipedia. Parameters `$m` `String` $text
`public`	# `_sha512( String $m )` Pure-PHP implementation of SHA384 and SHA512 Pure-PHP implementation of SHA384 and SHA512 Parameters `$m` `String` $text
`public Integer`	# `_rightRotate( Integer $int, Integer $amt )` Right Rotate Right Rotate Parameters `$int` `Integer` $int `$amt` `Integer` $amt Returns `Integer` See `Crypt_Hash::_sha256()`
`public Integer`	# `_rightShift( Integer $int, Integer $amt )` Right Shift Right Shift Parameters `$int` `Integer` $int `$amt` `Integer` $amt Returns `Integer` See `Crypt_Hash::_sha256()`
`public Integer`	# `_not( Integer $int )` Not Not Parameters `$int` `Integer` $int Returns `Integer` See `Crypt_Hash::_sha256()`
`public String`	# `_add( )` Add Add _sha256() adds multiple unsigned 32-bit integers. Since PHP doesn't support unsigned integers and since the possibility of overflow exists, care has to be taken. Math_BigInteger() could be used but this should be faster. Returns `String` See `Crypt_Hash::_sha256()`
`public String`	# `_string_shift( String & $string, optional $index = 1 )` String Shift String Shift Inspired by array_shift Parameters `$string` `String` $string `$index` `optional` Integer $index Returns `String`
