RE: Sha1 Conversion

Larry,

Are you converting the string 'abc' to ASCII before running the hash? It is
likely that the eCommerce application is using the ASCII character set and
the System I uses the EBCDIC character set. You can use the QDCXLATE or
ICONV APIs to do the character conversion.

Subject: Sha1 Conversion

Hello,

I am trying to create an RPG program to create an SHA-1 Hash to be used in
an Ecommerce application. I am using the API QC3CalHa to create the hash
value. I am successful in generating the 20 byte message digest (which is
in an unreadable format). However, I am unable to properly convert the
generated hashvalue to the proper format to be used in my webapp. I have a
test string that I was given with the expected results. The test string
'abc' should return the string
"a9993e364706816aba3e25717850c26c9cd0d89d". However, my program is
returning
"80ADD764A3B1057058473DC9FCC7B461DDD62749".

My problem is 1) I am unsure how to verify the message digest (hash)
created by QC3CALHA is correct? and 2) how to I successfully convert the
generated message digest into the correct format?

Any help would be greatly appreciated.
