hi all - I’m not sure if this is the correct forum but i was wondering if anyone has successfully done RSA-SHA1 signing with Ruby OpenSSL and interoperated with Java Servers. I’m using the following code but i’m not sure if the “sign” method on works properly - @key = OpenSSL::PKey::RSA.new(2048) #sign @key.send(“sign”, OpenSSL::Digest.::SHA1.new, “text to sign”) The expected signature from above “sign” is not what i know the Java crytpo api likes. Thanks in advance. regards, Vaibhav ---
