Decrypt2

See more MIME Examples

Demonstrates how to decrypt MIME using a certificate and private key where the certificate and its corresponding private key are stored in separate files -- a .cer for the certificate, and a .pem for the private key. Ruby

require 'chilkat'

success = false

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

mime = Chilkat::CkMime.new()

# Load the certificate from a .cer file.
cert = Chilkat::CkCert.new()
success = cert.LoadFromFile("aaworkarea/myCert.cer")
if (success == false)
    print cert.lastErrorText() + "\n";
    exit
end

# Load the private key from an encrypted PEM file.
# (A private key can be loaded from other file formats also..)
privKey = Chilkat::CkPrivateKey.new()
success = privKey.LoadEncryptedPemFile("aaworkarea/myPrivateKey.pem","myPassword")
if (success == false)
    print privKey.lastErrorText() + "\n";
    exit
end

success = mime.LoadMimeFile("aaworkarea/encryptedMime.txt")
if (success == false)
    print mime.lastErrorText() + "\n";
    exit
end

# Decrypt using the cert and associated private key
success = mime.Decrypt2(cert,privKey)
if (success == false)
    print mime.lastErrorText() + "\n";
    exit
end

# Save the S/MIME to a file.
success = mime.SaveMime("aaworkarea/decryptedMime.txt")
if (success == false)
    print mime.lastErrorText() + "\n";
    exit
end

print "success!" + "\n";
