# openssl-example
This repository contains examples to show how to use the OpenSSL C API.
## Build
```
cmake -B build
cmake --build build
./build/create_test_pki
```
## Glossary
| Abbreviation | Description |
| ------------ | ----------- |
| [X.509](https://en.wikipedia.org/wiki/X.509) | A standard defining the format of public key certificates |
| [CA](https://en.wikipedia.org/wiki/Certificate_authority) | **C**ertificate **A**uthority |
| [CSR](https://en.wikipedia.org/wiki/Certificate_signing_request) | **C**ertificate **S**igning **R**equest |
| [CRL](https://en.wikipedia.org/wiki/Certificate_revocation_list) | **C**ertififcate **R**evocation **L**ist |
| [CMS](https://en.wikipedia.org/wiki/Cryptographic_Message_Syntax) | **C**ryptographic **M**essage **S**yntax |
| [PKI](https://en.wikipedia.org/wiki/Public_key_infrastructure) | **P**ublic **K**ey **I**nfrastructure |
## Examples
- [compute SHA256 checksumn](doc/sha256.md)
- [create a self-signed certficate](doc/self_signed.md)
- [create a certificate signing request (CSR)](doc/create_csr.md)
- [sign a CRS](doc/sign_csr.md)
- [create a certificate revokation list (CRL)](doc/create_crl.md)
- [verify a certificate](doc/verify_cert.md)
- [create a digital signature using cryptographic message syntax (CMS)](doc/cms_sign.md)
- [verify a CMS signature](doc/cms_verify.md)
### Remarks
- Some of the examples make use of a [test PKI](doc/test_pki.md).
- 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.
