Description
Returns the result when the specified hashing algorithm is applied to the content of the file the name of which is passed as a parameter.
The result is a hexadecimal encoded character string, with a maximum length of 128 characters in the current implementation (with the SHA-512 algorithm).
Syntax
Result = &HASH_FILE(FileName;Algorithm)

Result |
Alphanumerical variable |
Hashing of the file content, encoded in hexadecimal or *BLANK in the event of an error (algorithm not supported, etc.). |
|
FileName |
Alphanumerical constant or variable |
Name of file to be processed. |
Mandatory parameter. |
Algorithm |
Alphanumerical variable or constant. |
Name of the hashing algorithm. The valid values depend on the execution platform and its configuration.
The MD5, SHA-1, SHA-256, SHA-384 and SHA-512 algorithms are supported on all the platforms. |
Mandatory parameter. |
Example
If "SIGNATURE" is a 128 character alphanumeric variable and "FILE_NAME" is a program variable:
SIGNATURE = &HASH_FILE(FILE_NAME;'SHA-512')
