libcrypt-smime-perl - 0.27-1+b1 main

Crypt::SMIME provides a class for handling S/MIME messages. It can sign,
verify, encrypt and decrypt messages.
.
Crypt::SMIME operates on email messages as simple strings, so there's no
particular integration with other MAIL::* or MIME::* modules. Rather, it
can co-operate with any module capable of accepting / outputting the entire
message as a single string.
