| Hi,
Wikipedia has some information.
What is produced by "dgst -sha" is what the above link is calling SHA-0 (originally just called SHA).
All the best, -Dave
Hi all,
Noob here. I recently discovered that the "-sha1" and "-sha" flags in the "openssl dgst" command produce different outputs. I thought those were the same algorithms but turns out they are not:
$ echo -n "password" | openssl dgst -sha 80072568beb3b2102325eb203f6d0ff92f5cef8e
$ echo -n "password" | openssl dgst -sha1 5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8
I am aware of SHA1 and the SHA-128 algorithm.
1. What algorithm is used to generate hash when I use the "-sha" option?
2. What could I have done to get this answer to #1 in a better way? I am asking this because I tried to find what algorithm is being used through the "help" option as well as trying to search via "man openssl" but couldn't find anything. I also did a basic search for "openssl sha vs sha1" and couldn't find any relevant results. If there was a better way to know more about this option (say by reading some documentation), I'd be glad to know about it.
Merry Christmas.
Regards, Swapnil
