Certificates and cryptographic keys

For secure and confidential communication the following cryptographic keys and certificates are available. You can choose between S/MIME encrypted email (which is supported by almost all email clients) and PGP (which is supported by fewer programs, but offers a better verification infrastructure).

S/MIME Email

NuAS CA root certificate: NuAS_CA.cer
Dr. Wolfram Schroers S/MIME email certificate: Dr._Wolfram_Schroers.cer

For verification please use the following fingerprints (these should always by verified by a direct and personal communication):
NuAS CA root certificate: SHA256 fingerprint=AC:A9:22:5B:32:13:65:7A:01:77:10:1F:2E:3D:D6:8E:A2:EF:BC:31:D4:50:62:98:87:67:89:12:F9:0C:43:81
Dr. Wolfram Schroers certificate: SHA256 fingerprint=80:95:BF:6D:BA:52:4B:28:7A:63:27:AF:A7:17:3E:6C:11:76:F2:0A:B5:A9:29:43:02:72:2C:48:1C:6D:95:67

In case your system does not have the NuAS root certificate installed please install that one first. For verification you should contact me personally and verify the fingerprint. You should subsequently adjust the trust settings to trust that certificate. Currently this certificate is used exclusively for emails that are encrypted and/or signed using S/MIME.

PGP

Dr. Wolfram Schroers PGP public key: Dr._Wolfram_Schroers.gpg2

For verification please use the following fingerprint:
Dr. Wolfram Schroers PGP public key: Key fingerprint = D0E1 3454 3250 11FE 9ADD 4DCA EA6E 8DE3 4D86 D326
