For encrypted communication we do support two mechanisms, GPG/PGP and S/MIME.
Please exchange the needed public keys (PGP) or certificates (S/MIME) with your communication partner at atsec.
For the latter, just send a signed e-mail to your atsec communication partner.
To facilitate the management of S/MIME certificates, we provide the CA certificate and the certificate revocation list (CRL) below:
To verify public keys or certificates, please contact your communication partner for finger-print verification.
