Overview ColdFusion Open BlueDragon Lucee

This function only exists for backward compstibility to Railo 4.0 or older version that has produced a incorrect result for non us-ascii caharacters, Only use this function for backward compatibility. 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

Attributes

Name Required Type Default Description

algorithm No 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.
