Evp

Evp evp – high-level cryptographic functions SYNOPSIS #include (openssl/evp.h) DESCRIPTION The EVP library provides a high-level interface to cryptographic func- tions. EVP_Seal… and EVP_Open… provide public key encryption and decryp- tion to implement digital “envelopes”. The EVP_Sign… and EVP_Verify… functions implement digital signa- tures. Symmetric encryption is available with the EVP_Encrypt… functions. The EVP_Digest… functions […]

Dynamic_pager

Dynamic_pager dynamic_pager — dynamic pager external storage manager SYNOPSIS dynamic_pager [-E] [-F filename] [-S filesize] [-H high-water-trigger] [-L low-water-trigger] [-P priority] DESCRIPTION The dynamic_pager daemon manages a pool of external swap files which the kernel uses to support demand paging. This pool is expanded with new swap files as load on the system increases, and […]
