Log Message:
-----------
Add API to enumerate supported cipher modes and hash algorithms
Implements issue #478 by introducing two new API functions:
- knet_get_crypto_cipher_list(): Returns AES cipher modes (CBC/CTR) supported across all crypto backends
- knet_get_crypto_hash_list(): Returns hash algorithms supported across all crypto backends
The functions return the intersection of capabilities across OpenSSL, NSS, and libgcrypt backends,
ensuring applications can reliably use any returned cipher/hash combination regardless of which
crypto module is loaded at runtime.
Key implementation decisions:
- Uses hardcoded lists to avoid loading all crypto modules unconditionally
- Flattened cipher list includes both OpenSSL (hyphenated) and NSS/gcrypt (non-hyphenated) naming
conventions as separate entries to simplify application logic
- Cipher list: 12 entries covering AES-128/192/256 in CBC and CTR modes
- Hash list: 5 entries covering md5, sha1, sha256, sha384, sha512
New structures:
- knet_crypto_cipher_info: name, mode, key_bits
- knet_crypto_hash_info: name, hash_bits
Includes comprehensive API tests following existing patterns.
