Near Term Plans¶
Here is an outline for the development plans over the next 12-24 months, as of February 2023.
Botan 2 is still supported, but no further feature work is planned. Only security issues and serious bugs will be addressed.
The following future work is currently planned for Botan 3:
BSI Project 481 [https://github.com/randombit/botan/issues/3108] will add several new post-quantum algorithms including SPHINCS+ signatures, LMS signatures, FrodoKEM, and Classic McEliece.
New ECC based password authenticated key exchanges, to replace SRP. The most likely candidate algorithms are CPace, OPAQUE, or SPAKE2+.
Adding an implementation of BLS12-381 elliptic curve pairing.
Low level integer math and elliptic curve arithmetic optimizations.
At this time there is no immediate plan for a new major version. When it occurs, it will remove functionality currently marked as deprecated, and adopt a new C++ version. This is unlikely to occur before 2026, at the earliest.
One major change already planned for Botan 4 is that in this release, Public_Key will no longer derive from Private_Key. And similarly, specific private keys (for example RSA_PrivateKey) will no longer derive from their cooresponding public key type.
