Bug #11774
Updated by nobu (Nobuyoshi Nakada) over 8 years ago
If we try to read out an RSA encrypted key with an invalid passphrase like so: ```ruby ``` require 'openssl' OpenSSL::PKey.read(File.read("#{ENV['HOME']}/.ssh/id_rsa"), 'invalid') ``` We get an argument error: ``` ArgumentError: Could not parse PKey: no start line from (pry):6:in `read' ``` However, if I understand the situation correctly, it should produce a decode error: `OpenSSL::PKey::RSAError`, as per the doc: > ``` OpenSSL::PKey::RSAError Generic exception that is raised if an operation on an RSA PKey fails unexpectedly or in case an instantiation of an instance of RSA fails due to non-conformant input data. ``` Reproduction: 1. 1) Create a password protected ssh key (if none exists): ``` ssh-keygen -t rsa -b 4096 ``` 2. 2) Run the following snippet (assuming ~/.ssh/id_rsa is the key location) ```ruby ``` require 'openssl' OpenSSL::PKey.read(File.read("#{ENV['HOME']}/.ssh/id_rsa"), 'invalid_passphrase') ``` Tested on: MacOSX 10.11.1 OpenSSL 1.0.2d 9 Jul 2015 Ruby 2.1.7 Ruby 2.2.3
