Interoperability and Certifications

The following provides an overview of EJBCA's capabilities and support, with relevant links to documentation and external standards. 

This is a selection of the most important standards and does not cover every specification EJBCA supports.

Specifications

Certificate Formats and Standards

EJBCA supports the following formats and standards.

CRL, OCSP and Certificate Distribution

EJBCA supports the following CRL formats and standards.

Algorithms and Key Types

EJBCA supports the following algorithm types and key size/curves. When using HSMs, support is limited to a subset by the PKCS#11 provider and the specific HSM used.

Algorithm	Key Size/curve	External Reference	Documentation
RSA	Keys up to and including 8192 bits.
DSA	Keys up to and including 1024 bits. Use of DSA is deprecated as of EJBCA 8.2.
ECDSA	Curves including named curves from Nist, SEC, Teletrust, and X9.62. For long term stability we recommend to use the most commonly used EC curves, if no other requirements apply choose P-256/P-384/P-521. View curves...
