* crypto: cipher - Add crypto_clone_cipherHerbert Xu2023-05-241-0/+2
| | | | | | | | | | | | | | Allow simple ciphers to be cloned, if they don't have a cra_init function. This basically rules out those ciphers that require a fallback. In future simple ciphers will be eliminated, and replaced with a linear skcipher interface. When that happens this restriction will disappear.

* crypto: remove cipher routines from public crypto APIArd Biesheuvel2021-01-021-0/+218
The cipher routines in the crypto API are mostly intended for templates implementing skcipher modes generically in software, and shouldn't be used outside of the crypto subsystem. So move the prototypes and all related definitions to a new header file under include/crypto/internal. Also, let's use the new module namespace feature to move the symbol exports into a new namespace CRYPTO_INTERNAL.
