Hash40

This function only exists for backward compstibility to Lucee 4.0 or older version that has produced an incorrect result for non us-ascii characters, Only use this function for backward compatibility, use Hash instead

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

Hash40( input [, algorithm [, encoding [, numIterations ] ] ] )

Returns: String

Argument Description
input
any, required

String to hash.

algorithm
string, optional

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

  • 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

A string specifying the encoding to use when converting the string to byte data used by the hash algorithm.

numIterations
number, optional

number of iterations; default is 1.
