Description: DeepCoder is a program to encrypt, decrypt and/or digitally sign e-mails and files using secret keys (passwords) or public keys. It can be used with any e-mail program or wordprocessor program. No plug-ins are required. Very easy to use and very straightforward! DeepCoder works with any POP3 e-mail client (like Outlook, Outlook Express, Eudora, Pegasus, ...) or a browser for webmail (Yahoo! mail, Hotmail, ...) to encrypt and decrypt e-mails.
