hi tony,
[ruby-core:68645] [Ruby trunk - Bug #8667] Unable to set OpenSSL GCM iv_length in Ruby
From:

List:
ruby-core #68645
Issue #8667 has been updated by Zachary Scott.
Assignee changed from Martin Bosslet to openssl
Without knowing what `HAVE_AUTHENTICATED_ENCRYPTION` is, I'm not really sure.. also we need a test for this.

Bug #8667: Unable to set OpenSSL GCM iv_length in Ruby

Hello,
In OpenSSL you are allowed to change the iv_length on an AES-BCM cipher. (
http://www.openssl.org/docs/crypto/EVP_EncryptInit.html#GCM_Mode) However
this was not implemented in the ruby-wrapper. Since I am a novice in C and
OpenSSL I think by no means my supplied patch is complete, it is a start
however. Maybe this missing function can be added to Ruby 2.0?
You can now set the iv_length using:
cipher = OpenSSL::Cipher.new('aes-128-gcm').encrypt
cipher.iv_len = 16
An issue I already spotted is that OpenSSL sets the ivlen on the
cipher_data (snippet from OpenSSL crypto/evp/e_aes.c):
EVP_AES_GCM_CTX *gctx = c->cipher_data;
gctx->ivlen = arg;
and not the c->cipher->iv_len. So querying for the iv_len in ruby by using
cipher.iv_len will still report the default which is 12. Encryption however
is done correctly using the new iv-length. I tested it by comparing it to
results from other programming languages (Java and C#).
Regards Andres
