[CipherMail User] Ciphermail suports ECDH?

[s.krause--- via Users]

Hi,

does anyone know, if ciphermail 5.1.3 supports ECDH Prime256 for S/MIME 
encryption??
RSA is working smooth but now we have one cert with ECDH and it shows cert key 
length -1.

I found not even one source which states out the supported algorythm of 
ciphermail.

Thanks in advance
Sebastian
