OpenSSL with Ruby

[vaibhavb]

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:Key::RSA.new(2048)
#sign
@key.send("sign", OpenSSL:igest.::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

after digging forums and searching through the source, this is what
i'm doing to sign:

digest = OpenSSL:igest::SHA1.new(text_to_sign)
sign = key.private_encrypt(digest)
# sign is what you want, if you need it in Base64:
enc_sign = Base64.encode64(sign)

enc_sign = Base64.encode64(sign)

Bawse64.encode64 is deprecated. Check out String#pack instead
(specifically the "m*" option).

I tried the above but it still is not same as Java output - I want to
be able to sign and update each byte of the text instead of string
(thats what Java does) .. any ideas?

Thanks in advance.

Hi Vaibhav,

Any chance you're dealing with a character encoding issue? By default
Java uses UTF-16. And you may be using UTF-8 with Ruby. Just a
thought....
