+ * \def MBEDTLS_BLOCK_CIPHER_NO_DECRYPT
+ *
+ * Remove decryption operation for AES, ARIA and Camellia block cipher.
+ *
+ * \note  This feature is incompatible with insecure block cipher,
+ *        MBEDTLS_DES_C, and cipher modes which always require decryption
+ *        operation, MBEDTLS_CIPHER_MODE_CBC, MBEDTLS_CIPHER_MODE_XTS and
+ *        MBEDTLS_NIST_KW_C. When #MBEDTLS_PSA_CRYPTO_CONFIG is enabled,
+ *        this feature is incompatible with following supported PSA equivalence,
+ *        PSA_WANT_ALG_ECB_NO_PADDING, PSA_WANT_ALG_CBC_NO_PADDING,
+ *        PSA_WANT_ALG_CBC_PKCS7 and PSA_WANT_KEY_TYPE_DES.
