注意：使用 OpenSSL 对文本进行对称加密。
我制作了一个 Ruby 脚本来测试 OpenSSL，但我发现我得到了不同的结果。密钥、iv 和密码是相同的，所以我希望结果是相同的。但他们不是。这是我的脚本：
require 'openssl'
require 'base64'
key = "00000000000000000000000000000000"
iv = "00000000000000000000000000000000"
### OPENSSL Command Line ###
puts "*** OpenSSL Command Line ***"
print "Encrypted via Command Line: "
string = `printf %s \"Hello\" | openssl enc -aes-128-cbc -K #{key} -iv #{iv} -base64`
puts string
puts string.inspect
print "Decrypted Data is: "
puts `printf %s \"BC2+AQJ6ZQx0al3GXba+EQ==\n\" | openssl enc -d -aes-128-cbc -K #{key} - iv #{iv} -base64`
puts "\n"
### Ruby OpenSSL Library ###
puts "*** OpenSSL Ruby Library ***"
cipher = OpenSSL::Cipher.new('aes-128-cbc').encrypt
cipher.padding = 1
cipher.key = key
cipher.iv = iv
encrypted_data = cipher.update("Hello")
encrypted_data << cipher.final
encrypted_data = Base64.encode64(encrypted_data)
puts "Encrypted via Ruby is: #{encrypted_data}"
puts encrypted_data.inspect
decipher = OpenSSL::Cipher.new('aes-128-cbc').decrypt
decipher.key = key
decipher.iv = iv
data = decipher.update(Base64.decode64(encrypted_data))
data << decipher.final
puts "Decrypted Data: #{data}"
结果是：
*** OpenSSL Command Line ***
Encrypted via Command Line: BC2+AQJ6ZQx0al3GXba+EQ==
"BC2+AQJ6ZQx0al3GXba+EQ==\n"
Decrypted Data is: Hello
*** OpenSSL Ruby Library ***
Encrypted via Ruby is: ZkeNEgsUXi1J7ps6kCQxdQ==
"ZkeNEgsUXi1J7ps6kCQxdQ==\n"
Decrypted Data: Hello
只是一个奇怪的结果。知道是什么导致数据不同吗？
