Status: Verified
SYMPTOM(s):
Using SHA1-DIGEST function to hash data
Result returned by Progress differs from the result generated in other tools
SHA1-DIGEST("The quick brown fox jumps over the lazy dog") returns:
020014L9ThxnotKPzthJ7hu3bnORuT6xI=
Other resource return the following result for the same string:
2fd4e1c67a2d28fced849ee1bb76e7391b93eb12
FACT(s) (Environment):
OpenEdge 10.x
All Supported Operating Systems
CAUSE:
This is expected and correct behaviour. The SHA1-DIGEST function is returning the correct result but in RAW format. As stated in the function documentation:
"[SHA1-DIGEST] returns a 20-byte binary message digest value as a RAW value."
FIX:
Use the HEX-ENCODE function to convert the RAW value returned by SHA1-DIGEST into a character string. This will show that:
020014L9ThxnotKPzthJ7hu3bnORuT6xI=
Is the same as:
2fd4e1c67a2d28fced849ee1bb76e7391b93eb12
