19.1.0-preview1

New Features

• Incremental hashing and MACing
• Algorithms
  • Hash: SHA-512-256
  • MAC: HMAC-SHA256-128, HMAC-SHA512-256

(I.e., truncated SHA-512, HMAC-SHA256, and HMAC-SHA512. These are not to be confused with SHA-512/256, HMAC-SHA256/128, and HMAC-SHA512/256, respectively, which not only truncate but additionally also use a different initial hash value.)
