We've decided to make these changes backward compatible, so this PR needs some changes

Comment 1: Typo (line 301, 379)

"doesn not" → "does not"

Comment 2: Misleading variable names (lines 316, 391)

cbc_encrypt/cbc_decrypt → encrypt/decrypt (now handles both CBC and GCM)

Comment 3: Simplify AEAD validation (lines 292-302, 346-352)

Validation is scattered across the function. Consider consolidating into one block. Also, line 348's warning says "when using AEAD mode" but is reached when NOT in AEAD mode.

Comment 4: Add comment (line 234-238)

Consider adding a comment that IV length validation is handled by the crypto component (differs from legacy runtime).

Comment 5: Missing GCM in cipher methods (lines 268-272)

Add AES_128_GCM and AES_256_GCM to the return value.

1. fixed typos
2. renamed
3. removed tag validation after response receivement
4. I don't see the point of adding this comment, because a lot of operations moved to crypto component, differently from the old runtime
5. added
