The 16-byte tag size is always calculated, and in your case it is appended. More details; WebMar 6, 2024 · GHASH, which is part of GCM, will be accelerated using pclmulqdq on Intel x64 and xmul / xmulhi on SPARC. RSA will be accelerated by using Bit Manipulation Instruction Set 2. It is likely that other asymmetric algorithms will benefit from from these changes, but they will be measured by RSA.
