int AES_set_encrypt_key(const unsigned char *userKey, const int bits,AES_KEY *key); 设定加密用的Key; userKey: 密钥数值。 bits:密钥长度,以bit为单位。假设密钥数字是16个字节,则此參数值应为128。 key: AES_KEY对象指针; 返回值: 0 成功, -1 userkey,key为空, -2: 密钥长度不是128。192。...
my_AES_cbc_encrypt 我自己写的AES-CBC加密和解密,调用了openSSL的AES_encrypt和AES_decrypt,想学习AES怎么用看看这个函数就可以了 aes_encrypt AES加密,调用了openSSL的AES_set_encrypt_key和我自己写的my_AES_cbc_encrypt,为了方便把明文长度作为第一个数据块 aes_decrypt AES解密,调用了openSSL的AES_set_decrypt...

以aes_generic算法为例,其密钥设置实现如下: int crypto_aes_set_key(struct crypto_tfm *tfm, const u8 *in_key, unsigned int key_len) { struct crypto_aes_ctx *ctx = crypto_tfm_ctx(tfm); (1) return aes_expandkey(ctx, in_key, key_len); (2) ...
crypto_skcipher_setkey：设置密钥。 build_cipher_test_sglists：创建sglist。 skcipher_request_set_callback：设置回调函数。 skcipher_request_set_crypt：设置加解密参数。 crypto_skcipher_encrypt：执行加密操作。类似地，hash流程也包括tfm和request分配、密钥设置（取决于算法）、sglist填充和摘要...
