fa26d13016 RSA: update documentation (crypt.tex) to reflect the latest changes 2026-04-15 11:12:30 +02:00
Steffen Jaeckel
66e677aedd Introduce new RSA API. 
This also:
a) deprecates the old RSA and PKCS#1 API.
b) reverts the changes done to them in order to make the now deprecated API
   compatible again with the last release.

The fixes commit mentioned below is the testcase for the Bleichenbacher
attack, which works now again as expected.

Fixes: 9d03c38e ("add flags to `der_decode_sequence()`")

ad2696f24f Update SIV a bit 
* Rename `siv_{en,de}crypt()` to `siv_{en,de}crypt_memory()`.
* The number of AAD components per SIV operation must not exceed 126.
* Init OMAC only once per SIV operation.
  All OMAC operations start off with the same key. Instead of
  re-initializing the OMAC context for each operation, init once and
  store the context.
* Add SIV to timing demo.
* Add 1000-times-encrypt-then-decrypt test for SIV.
* Update docs.

c0be0aa0bf Add support for more types of encrypted PEM files 
1. ChaCha20, two-key 3DES and DES-X encrypted OpenSSL PEM files

2. AES-GCM and Chacha20+Poly1305 encrypted SSH keys

* OpenSSH uses a slightly different algorithm for its
  `chacha20-poly1305@openssh.com` than defined in the RFC.
  Therefore add an `openssh_compat` flag to
  `chacha20poly1305_state`.
* Add the option to give a 16byte IV and no counter, when calling
  `chacha20poly1305_memory()`
* Add support for DES-X
