Is there a way to get the modulus and exponent from an key, or is there
a way to get that information as it is being encrypted? I am using the
OpenSSL:
Key::RSA library to encrypt my data. Thanks,
It's in ext/openssl/ossl_pkey_rsa.c
ssl_rsa_get_params
sh-2.05b$ openssl genrsa -out test.pem 512
Generating RSA private key, 512 bit long modulus
......++++++++++++
++++++++++++
e is 65537 (0x10001)
sh-2.05b$ cat sslparams.rb
require 'openssl'
file = ARGV[0] || "test.pem"
OpenSSL:
Key::RSA.new(File.read(file)).params.each do |k,v|
puts "#{k} = #{v}"
end
sh-2.05b$ ruby sslparams.rb
