| * If a cipher or AEAD mechanism has a PSA driver, you can now build the | |
| library without the corresponding built-in implementation. Generally | |
| speaking that requires both the key type and algorithm to be accelerated | |
| or they'll both be built in. However, for CCM and GCM the built-in | |
| implementation is able to take advantage of a driver that only | |
| accelerates the key type (that is, the block cipher primitive). See | |
| docs/driver-only-builds.md for full details and current limitations. | |
| * The CTR_DRBG module will now use AES from a PSA driver if MBEDTLS_AES_C is | |
| disabled. This requires PSA_WANT_ALG_ECB_NO_PADDING in addition to | |
| MBEDTLS_PSA_CRYPTO_C and PSA_WANT_KEY_TYPE_AES. |
