I've wrote a simple script to sign and verify some text and generate a
PKCS7 using OpenSSL.

  require 'openssl'
  include OpenSSL

  data = 'abcdefghijklmnsopqrstuvwxyz\n'

  cert = X509::Certificate.new( File::read("my_cert.pem") )
  prv_key = PKey::RSA.new( File::read("key_prv.pem") )

  store = X509::Store.new
  store.add_cert(cert)

  #gen sign
  p7 = PKCS7.sign(cert,prv_key,data)

  #verify sign
  puts "verified: #{p7.verify([cert],store,data,0)}"

executed, the result is:

  verified: true

but changing the data variable from sigle quoted to double quoted:

  data = "abcdefghijklmnsopqrstuvwxyz\n"

the answer is:

  verified: false

i know that escaped characters are treated diferently within double
quoted strings, but i sign and verify the same data in both cases.
 ¿what's happen?


this is the content of the file 'my_cert.pem'
