Would you use HMAC-SHA1 or HMAC-SHA256 for message authentication? Yes. That is a semi-serious answer; both are very good choices, assuming, of course, that a Message Authentication Code is the appropriate solution (that is, both sides share a secret key), and you don't need extreme speed.

At the moment, Java 8 and Java 11 are the LTS (long-term support) versions. The end of public updates for Java 8 is scheduled for January of 2019 for commercial use. Completes the HMAC computation and resets the HMAC for further use, maintaining the secret key that the HMAC was initialized with.

Creates a keyed-hash message authentication code (HMAC), which can be used to verify authenticity and integrity of a message by two parties that share the key.

Remarks. HMACSHA1 is a type of keyed hash algorithm that is constructed from the SHA1 hash function and used as an HMAC, or hash-based message authentication code. The HMAC process mixes a secret key with the message data, hashes the result with the hash function, mixes that hash value with the secret key again, and then applies the hash function a second time. HmacAlgorithms (Apache Commons Codec 1.14 API) HMAC_SHA_224 public static final HmacAlgorithms HMAC_SHA_224. The HmacSHA224 Message Authentication Code (MAC) algorithm specified in RFC 2104 and FIPS PUB 180-2. Every implementation of the Java 8+ platform is required to support this standard MAC algorithm. Since: 1.11; HMAC_SHA_256 java - Generating HMAC - Code Review Stack Exchange HMAC.java:75, why new Hex();? That's not used anywhere. As an example for "too much code",Posix.java:49, the whole method can just be return new PosixParser().parse(comOptions, args); with no loss of functionality. Some of these things can also be discovered by automatic checkers like CheckStyle, PMD and so on. Some will also warn about package hmac Code Examples and CFML Documentation hmac.
