MD5 Subroutine

Usage:

hash = MD5(file_or_data [, option_flags])

Description:

Returns a MD5 hash (or empty string on error) of a file or data provided to the subroutine. The optional option_flags parameter determines what to hash as well as how to return the hash value. The option flags are set using bits 0 and 1 as follows:

Bit 0 Clear = file_or_data contains the name of a file to hash.
Set = file_or_data contains the (string or binary) data to hash;

Bit 1 Clear = return the hash as a string value.
Set = return the hash as a binary value.

Example:

sub main()

// note: to set bit 0 we use the value 1 and to set bit 1

// we use the value 2. To set both bits we simply add the

// values together 1+2=3.

printl("The MD5 hash of string ABC is: " # MD5("ABC", 1))

printl("The MD5 hash of file FILE.EXT is: " # MD5("FILE.EXT"))

binary_data_hash=MD5("string", 3)

binary_file_hash=MD5("d:\path\file", 2)

end sub
