Overview
Product summary
Review the store description, core capabilities, and common use cases.
Send and receive encrypted email messages using the S/MIME technology. CypherMail allows to exchange encrypted email messages. The encryption is S/MIME standard, the solution recommended by the security experts, and it is based on certificates. The certificates are generated on the fly when an email address is used. They are issued by an internal PKI that generated certificates with emailProtection key extended usage.
The main CypherMail features are:
- S/MIME 3.1 (X.509, RFC 3280) email encryption.
- Compatible with existing S/MIME clients (like Outlook, Thunderbird etc.).
- Certificates for S/MIME email encryption are automatically generated for each contact.
- PKI included in the solution to issue the certificates.
