Does ciphermail support the signature scheme
RSASSA-PSS (PKCS #1 v2.1)?
And if so, how is it configured?
Since ciphermail version 2.5.0-04 there is support for S/MIME v3.2 as
described in rfc5751. This RFC denotes RSASSA-PSS as "SHOULD+". I didn't
find any reference to it in ciphermail documentation.
I forgot to add that even though S/MIME v3.2 says it should be
supported, to my knowledge no email client currently supports
RSASSA-PSS. Only really recent versions of OpenSSL support RSASSA-PSS
but Outlook, Thunderbird etc. do not support RSASSA-PSS nor RSAES-OAEP.
The upcoming CipherMail gateway does so will be able to use gateway to
gateway encryption/signing using RSASSA-PSS and RSAES-OAEP.
CipherMail email encryption
Email encryption with support for S/MIME, OpenPGP, PDF encryption and
secure webmail pull.
