AES全称为Advanced Encryption Standard,是一种对称分组算法。AES算法是NIST组织公开竞选产生,最终Rijndael力压群雄,在2000年被NIST选择为AES标准算法。通过AES算法可以加密或解密一段数据,其中加密为将明文转换为密文,解密是将密文转换为明文。AES算法的密钥长度有三种:128bits、192bits、256bits,但加密和解密的分组长度必...

Fix a build failure that occurred with the MBEDTLS_AES_SETKEY_DEC_ALT option on. In this configuration key management methods that are required for MBEDTLS_CIPHER_MODE_XTS were excluded from the build and made it fail. Fixes#3818. Reported by John Stroebel. ...
