String Encryption Functions

String Encryption Functions
crc32()
integer crc32(string $sMessage)
This function returns the cyclic redundancy checksum polynomial value of $sMessage. This is used for error detection when transmitting data.
Argument	Description
string $sMessage	This is the string for which the checksum is calculated.
crypt()
string crypt(string $sMessage, string $sSalt = default)
This function returns the hashed string for $sMessage, applying the $sSalt string. The following encryption algorithms are available: CRYPT_STD_DES CRYPT_EXT_DES CRYPT_MD5 CRYPT_BLOWFISH CRYPT_SHA256 CRYPT_SHA512
Argument	Description
string $sMessage	This is the string for which the hashed string is being created.
string $sSalt	This is the string that is used to encode the message.
md5()
string md5(string $sMessage, bool $bOutputRaw = false)
This function returns md5 hash of $sMessage.
Argument	Description
string $sMessage	This is the string for which the hash is calculated.
bool $bOutputRaw	This determines whether the digest should be returned instead.
metaphone()
string metaphone(string $sMessage, integer $iLimitToPhonemes = 0)
This function returns the metaphone key of $sMessage.
Argument	Description
string $sMessage	This is the string for which the metaphone is calculated.
integer $iLimitToPhonemes	This determines whether returned string length. The value 0 means that there is no limit.
sha1()
string sha1(string $sMessage, bool $bOutputRaw = false)
This function returns sha1 hash of $sMessage.
Argument	Description
string $sMessage	This is the string for which the hash is calculated.
bool $bOutputRaw	This determines whether the digest should be returned instead.
soundex()
string soundex(string $sMessage)
This function returns the soundex key of $sMessage.
Argument	Description
string $sMessage	This is the string for which the soundex is calculated.
str_rot13()
string str_rot13(string $sMessage)
This function returns the rot13 encoding of $sMessage.
Argument	Description
string $sMessage	This is the string for which the rot13 is calculated.
