PKI 9 Configuring SCEP Responder - dogtagpki/pki GitHub Wiki

The SCEP responder can be configured in /var/lib/pki-ca/conf/CS.cfg:

ca.scep.enable=true
ca.scep.encryptionAlgorithm=DES3
ca.scep.allowedEncryptionAlgorithms=DES,DES3
ca.scep.hashAlgorithm=SHA1
ca.scep.allowedHashAlgorithms=SHA1,SHA256,SHA512
ca.scep.nonceSizeLimit=16

SCEP supports usage of its own key pair, which can be configured by adding the following line:

ca.scep.nickname=scepSigningCert cert-pki-ca
ca.scep.tokenname=Internal Key Storage Token

to the SCEP section of /var/lib/pki-ca/conf/CS.cfg.

Keep in mind that to enable separate SCEP key pair:

  • new SCEP key pair has to be designated

  • SCEP certificate has to be created

  • SCEP certificate has to be imported to NSS-DB using scepSigningCert cert-pki-ca as its nickname

SCEP support for its own key pair was tested using existing OCSP keys and certificate. Test was configured by adding the following line:

ca.scep.nickname=ocspSigningCert cert-pki-ca
ca.scep.tokenname=Internal Key Storage Token

to the SCEP section of /var/lib/pki-ca/conf/CS.cfg.

Note that ca.crt was replaced by ocsp.crt.

$ sscep enroll \
    -u http://<hostname>:9180/ca/cgi-bin/pkiclient.exe \
    -c ocsp.crt \
    -k local.key \
    -r local.csr \
    -E 3des \
    -S sha256 \
    -l cert.crt \
    -d

Add IP address and password to /var/lib/pki-ca/conf/flatfile.txt. Leave empty line between and after each pair of lines containing UID and PWD.
