Lesson plan
Libgcrypt
Libgcrypt is a cryptography library developed as a separated module of GnuPG. It can also be used independently of GnuPG, but depends on its error-reporting library Libgpg-error. It provides functions for all fundamental cryptographic building blocks: Libgcrypt features its own multiple precision arithmetic implementation, with assembler implementations for a variety of processors, including Alpha, AMD64, HP PA-RISC, i386, i586, M68K, MIPS 3, PowerPC, and SPARC. It also features an entropy gathering utility, coming in different versions for Unix-like and Windows machines. Usually multiple, stable branches of Libgcrypt are maintained in parallel; as of May 2026 this is the Libgrypt 1.12 branch as LTS ("long-term support") branch, the 1.11 branch as previous stable branch, which will be maintained at least until 2028-06-30 , and the 1.8 branch as "old-LTS" branch, which is still maintained as long a customer with an "extended Long Term Support contract" exists, despite its original end-of-life date being 2024-12-31.
