| Abbreviation | Description |
|---|---|
| X.509 | A standard defining the format of public key certificates |
| CA | Certificate Authority |
| CSR | Certificate Signing Request |
| CRL | Certififcate Revocation List |
| CMS | Cryptographic Message Syntax |
| PKI | Public Key Infrastructure |
- compute SHA256 checksumn
- create a self-signed certficate
- create a certificate signing request (CSR)
- sign a CRS
- create a certificate revokation list (CRL)
- verify a certificate
- create a digital signature using cryptographic message syntax (CMS)
- verify a CMS signature
- Some of the examples make use of a test PKI.
- The purpose of this repository is to give an overview about OpenSSL's C API. Therefore, there is almost no error handling contained in the examples.
- OpenSSL>3.0
