1OpenSSL Demonstration Applications 2 3This folder contains source code that demonstrates the proper use of the OpenSSL 4library API. 5 6Note: Makefiles are provided in the demo subfolders to demonstrate how to build 7them, but are not frequently used. Configure openssl with enable-demos to build 8them automatically through the perl based build system 9 10bio: Demonstration of a simple TLS client and server 11 12certs: Demonstration of creating certs, using OCSP 13 14cipher: 15aesgcm.c Demonstration of symmetric cipher GCM mode encrypt/decrypt 16aesccm.c Demonstration of symmetric cipher CCM mode encrypt/decrypt 17ariacbc.c Demonstration of symmetric cipher CBC mode encrypt/decrypt 18 19cms: Demonstrations related to the Cryptographic Message 20 Syntax (CMS) standard 21 22digest: 23EVP_MD_demo.c Compute a digest from multiple buffers 24EVP_MD_stdin.c Compute a digest with data read from stdin 25EVP_MD_xof.c Compute a digest using the SHAKE256 XOF 26EVP_f_md.c Compute a digest using BIO and EVP_f_md 27 28encode: 29rsa_encode.c Encode and decode PEM-encoded RSA keys 30 31encrypt: 32rsa_encrypt.c Encrypt and decrypt data using an RSA keypair. 33 34guide: Sample code from the OpenSSL Guide tutorials.
