我收到错误:
unsupported cipher algorithm (AES-256-GCM) (RuntimeError)
但我似乎有所有要求:
Ruby版本:
$ruby –version
ruby 2.1.2p95
OpenSSL确实列出了gcm:
$openssl enc -help 2>&1 | grep gcm
-aes-128-ecb -aes-128-gcm -aes-128-ofb
-aes-192-ecb -aes-192-gcm -aes-192-ofb
-aes-256-ecb -aes-256-gcm -aes-256-ofb
Ruby解释器:
$irb
2.1.2 :001 > require ‘openssl’; puts OpenSSL::VERSION
1.1.0
=> nil
2.1.2 :002 > OpenSSL::Cipher.ciphers.include? “aes-128-gcm”
=> true
- 2.1.2 :001 > require 'openssl'
- => true
- 2.1.2 :002 > cipher = OpenSSL::Cipher::AES.new(128,:GCM)
- RuntimeError: unsupported cipher algorithm (AES-128-GCM)

如何让GCM在ruby中工作?
