Use an XmlCertVault for S/MIME Operations

See more MIME Examples

Loads a CMS/PKCS #7 encrypted S/MIME message and decrypts it back to the original MIME content.

UseCertVault sets an XmlCertVault as the single active source of certificates and private keys for S/MIME encryption, decryption, signing, and verification.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

require 'chilkat'

success = false

mime = Chilkat::CkMime.new()
success = mime.LoadMimeFile("qa_data/encrypted.eml")
if (success == false)
    print mime.lastErrorText() + "\n";
    exit
end

#  Use an XmlCertVault as the source of certificates and private keys for S/MIME operations.  The
#  only argument is the vault.  Only one vault is active at a time.
vault = Chilkat::CkXmlCertVault.new()
pfxPassword = "myPfxPassword"
success = vault.AddPfxFile("qa_data/recipient.pfx",pfxPassword)
if (success == false)
    print vault.lastErrorText() + "\n";
    exit
end

success = mime.UseCertVault(vault)
if (success == false)
    print mime.lastErrorText() + "\n";
    exit
end

#  Decryption (and signing/verification) now draws credentials from the vault.
success = mime.Decrypt()
if (success == false)
    print mime.lastErrorText() + "\n";
    exit
end

print "Decrypted using the certificate vault." + "\n";
