Libgcrypt

Libgcrypt is a cryptography library developed as a separated module of GnuPG.[5] It can also be used independently of GnuPG, but depends on its error-reporting library Libgpg-error.[6]

key derivation functions (KDFs):[15] S2K (as in RFC 4880: simple, salted, iterated+salted), PBKDF2, SCRYPT, Argon2d, Argon2i, Argon2id, Balloon
elliptic curves: NIST (P-256, P-384, P-521), SECG (secp256k1), ECC Brainpool / RFC 5639 (P256r1, P384r1, P512r1), Bernstein (Curve25519, Curve448), GOST R 34.10-2012 (RFC 7091), SM2[16]

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; since 2022-03-28 this is the Libgrypt 1.10 branch as stable branch, plus the 1.8 branch as LTS ("long-term support") branch, which will be maintained at least until 2024-12-31.[17]
