Which PGP standards are supported
The mail encryption used by mailbox Guard is 100% compatible with the (Open)PGP standard.
PGP/MIME and PGP/Inline encrypted mails can be sent, received, signed, and verified in the mailbox web client. This allows you to communicate securely via mail with users of other PGP-compatible mail clients or plug-ins without any issues.
Mailbox Guard currently supports so-called ECC PGP keys (Elliptic Curve Cryptography) according to RFC 6637.
