MD5digest (String function)

16-byte MD5 digest (String class)

This intrinsic function returns the 16-byte (always) binary string that is the MD5 digest (hash) of the method object string.

The MD5digest function is available as of version 7.3 of the Sirius Mods.

Syntax

%outString = string:MD5digest

Syntax terms

%outStr	A string variable to receive the MD5 digest of the method object string.
string	The string to which the method is applied.

Usage notes

• MD5 (Message-Digest algorithm 5) is a well-known cryptographic hashing function which is used in the Janus Network Security product for digital signatures. A complete explanation of MD5 hashing can easily be found on the Internet.
• MD5digest is available for use by Janus SOAP or Janus Network Security customers.
• SHAdigest returns the SHA digest of the method object string, and RC4encrypt (:hdref refid=strc4ed.) returns the RC4 encryption of the method object string.

Examples

The 16-byte MD5 hash of a string is typically expressed as a 32-digit hex value. In the following example, the output string from the MD5digest method is converted to hex using the StringToHex intrinsic method:

printText {'this is a test':md5digest:stringtohex}

The result (displayed on two lines) is:

'this is a test':md5digest:stringtohex is 9034E10B7993EB846B6D127070E71E25
