WebIntroduction ¶. The kernel crypto API offers a rich set of cryptographic ciphers as well as other data transformation mechanisms and methods to invoke these. This document contains a description of the API and provides example code. To understand and properly use the kernel crypto API a brief explanation of its structure is given. WebThe Crypto.Cipher package contains algorithms for protecting the confidentiality of data. Symmetric ciphers: all parties use the same key, for both decrypting and encrypting data. Symmetric ciphers are typically very fast and can process very large amount of data. Asymmetric ciphers: senders and receivers use different keys. brathaus richmond il
