20-byte SHA digest (String class)
The SHAdigest intrinsic function returns the 20-byte (always) binary string that is the SHA digest of the method object string.
Syntax
%outString = string:SHAdigest
Syntax terms
| %outString | A string variable to receive the SHA digest of the method object string. |
|---|---|
| string | The string to which the method is applied. |
Usage notes
- SHA (Secure Hash Algorithm) is a set of cryptographic hashing functions; SHAdigest provides SHA-1, the most commonly used. A complete explanation of SHA hashing can easily be found on the internet.
- This method is useful for storing one-way encrypted passwords in a file. SHA is considered unreversible. That is, the only way to get a password given a digest is brute force: trying passwords until one produces the digest (more or less a hash) value.
- SHAdigest is available for use by Janus SOAP or Janus Network Security customers.
- SHAdigest is available as of Sirius Mods Version 7.3.
Examples
The 20-byte SHA hash of a string is typically expressed as a 40-digit hex value. In the following example, the output string from the SHAdigest method is converted to hex using the StringToHex intrinsic method:
printText {'this is a simple test':shadigest:stringtohex}
The result (displayed on two lines) is:
'this is a simple test':shadigest:stringtohex is BC38AA2D6769639946806616C14AF0C69477AABE

- MD5digest returns the MD5 digest of the method object string, and RC4encrypt returns the RC4 encryption of the method object string.
