string.hash()

edit

Converts a variable-length string to a 32-byte, hexadecimal string, using the MD5 algorithm. (It is not possible to convert the hash result back to the source string.) 32-byte, hexadecimal string

string.hash( algorithm=string, encoding=string, numIterations=number )

Returns: String

Argument Description
algorithm
string, optional 		edit

The algorithm to use to hash the string. Supported are the following algorithms:

  • QUICK: generating a fast hash string, that provides no security. this algorithm is good when you simply need to shorten a string for an id, for example
  • CFMX_COMPAT: generating a hash string using classic CFML algorithm.
  • MD5: (default) Generates a 32-character, hexadecimal string, using the MD5 algorithm.
  • SHA: Generates a 28-character string using the Secure Hash Standard SHA-1 algorithm specified by Nation Institute of Standards and Technology (NIST) FIPS-180-2.
  • SHA-256: Generates a 44-character string using the SHA-256 algorithm specified by FIPS-180-2.
  • SHA-384: Generates a 64-character string using the SHA-384 algorithm specified by FIPS-180-2.
  • SHA-512: Generates an 88-character string using the SHA-1 algorithm specified by FIPS-180-2.
encoding
string, optional 		edit

A string specifying the encoding to use when converting the string to byte data used by the hash algorithm.
numIterations
number, optional 		edit

The number of times to iterate hashing. A greater number of iterations will result in a cryptographically stronger hash but will also take more time to generate that hash. The default value is 1. For algorithm quick, only 1 is allowed
