I am having problems matching up a signature created with openssl on
the command line with a signature created in Ruby.
The signature I am trying to get is an RSA encryption with my 1024
bit private key of a SHA-1 hash of data.
This is what I did on the command line:
$ openssl genrsa -out private.pem 1024
$ echo -n “Some text to sign”
| openssl dgst -sha1 -binary
| openssl rsautl -sign -inkey private.pem
| openssl enc -base64
This is what I did in Ruby:
private_key = RSA.new(File.open("/Users/andy/tmp/private.pem").read)
signature = private_key.sign(OpenSSL::Digest::SHA1.new, “Some text
Unfortunately the base64-encoded signatures produced by each method
I have spent quite a lot of time with Google and the RubyPKI source
– but I am new to Ruby and have exhausted all the avenues I can
Any help would be much appreciated.
Thanks and regards,
