undefined method 'iv_len=' for #<OpenSSL::Cipher

[arpriego88]

I have scenario where I need to change the iv length from 12 to 16. I am able to do this when in an IRB console using ruby-2.6.3:

require 'openssl'
 => true
cipher = OpenSSL::Cipher.new("aes-256-gcm")
 => #<OpenSSL::Cipher:0x00007fc4bd9e94c0>
cipher.decrypt
 => #<OpenSSL::Cipher:0x00007fc4bd9e94c0>
cipher.iv_len = 16
 => 16

cipher.methods
 => [:encrypt, :decrypt, :pkcs5_keyivgen, :final, :key=, :auth_data=, :auth_tag=, :auth_tag, :auth_tag_len=, :authenticated?, :key_len=, :key_len, :iv=, :iv_len=, :iv_len, :name,

However when using jruby-9.2.13.0 I get:

require 'openssl'
 => true
cipher = OpenSSL::Cipher.new("aes-256-gcm")
 => #<OpenSSL::Cipher:0x285c6918>
cipher.decrypt
 => #<OpenSSL::Cipher:0x285c6918>
cipher.iv_len
 => 12
cipher.iv_len = 16

Did you mean?  iv_len

# missing iv_len=

Will this be a pain to add?

I have no idea why my specs are failing if someone smarter than me would like to help me out with this, I'd greatly appreciate it!
