How to use GnuPG to generate sha512sum hash?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi list, I want hash some strings by using GnuPG, I know GPG have hash function, but I can't find how to do it in the manuals or other documentations on the official website. What's parameters used by GPG for hash? Furthermore, I would like use sha-512 hash strings from standard input, rather than from files, is it possible? If not, is there any other app can do this for me?

Hi, (Sorry for last mail, FireGPG truncated my mail...so here it should be) Thank you for your reply, it works. But hash results that I got from GPG is different from some web based hash calculator, such as, http://www.johnmaguire.us/tools/hashcalc/ or http://people.eku.edu/styere/Encrypt/JS-SHA1.html e.g. for AAA, web based SHA1 result is: 606ec6e9bd8a8ff2ad14e5fade3f264471e82251 , and SHA512 result is: 8d708d18b54df3962d696f069ad42dad7762b5d4d3c97ee5fa2dae0673ed46545164c078b8db3d59c4b96020e4316f17bb3d91bf1f6bc0896bbe75416eb8c385 but GPG's result is: echo AAA | gpg --print-md SHA1 1AE0 9EE3 43FA 9C61 8DE7 C5C1 770E F4E4 90B2 4ADA echo AAA | gpg --print-md SHA512 1CD99029 6017D85F 8B909505 21AE360D C8D907C3 A09B14AB 5B273F85 7BC2F166 B90B3889 07DF7A7C A383D585 D555F383 92B1101E 0A2B1829 0D966F54 25036FDB Due to I have try more than one web-based cryptographic hash calculator. I don't think online results are wrong. All of them generates the same results except GPG. Did I miss something? Or it's a issue of my GPG installation? Best regards.

I don't think online results are wrong. All of them generates the same results except GPG. You are making a mistake with echo. By default, echo adds a newline at the end of what it prints. You are hashing AAA on the website, and AAA\n with GPG, so naturally they don't match. Add the -n flag to echo to tell it to not add a newline, and you will see the results match: echo -n AAA | gpg --print-md sha512 David ___ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
Re: How to use GnuPG to generate sha512sum hash?
O...I see. I've get the correct hash on Linux..., thank you all! :-) The problem remains now is how to get the same hashing on Windows, because echo on windows does not have -n flag: echo -n AAA -n AAA so, on windows echo -n AAA | gpg --print-md sha1 is actually hashing -n AAA\n but not AAA... :-\ Is there a easy way to get rid of the newline on windows system?
