opmsg

opmsg is a replacement for gpg which can encrypt/sign/verify your mails or
create/verify detached signatures of local files. Even though the opmsg
output looks similar, the concept is entirely different.

Perfect Forward Secrecy (PFS) by means of ECDH or DH Kex.
Native EC or RSA fallback if no (EC)DH keys left.
Signing messages is mandatory.
OTR-like deniable signatures if demanded.
Support for 1:1 key bindings to auto-select source key per
destination.
Adds the possibility to (re-)route messages different from mail
address to defeat meta data collection.
Key format suitable for easy use with QR codes.
Optional cross-domain ECDH Kex.
