根据维基百科里的说法,AES 的 key size 只支持 128 bits, 192 bits, 256 bits 对方提供的对接接口中的KEY的长度是 32 理应对应aes-256却调用了aes-128,实际只利用了前 16 个字符,因为本身 32 大于 16 调用aes-128的时候会只读前面的 16,而且能读到,便没有报错。 对接接口么,一般就直接把KEY复制过来传进...

intAES_set_encrypt_key(constunsigned char*userKey,constint bits,AES_KEY*key); userKey:指向用于设置密钥的输入数据的指针,即原始密钥。 bits:密钥长度,以比特为单位。在使用 AES 加密算法时,通常为 128、192 或 256。 key:指向AES_KEY结构的指针,用于存储设置后的密钥信息。
我个人感觉是秘钥长度 就是128、192、256 位三种,我尝试用 Java (BouncyCastle 包)实现 AES 给出非 128、192、256 位的秘钥抛出这个异常似乎也是一种佐证 org.bouncycastle.jcajce.provider.symmetric.util.BaseBlockCipher$1: Key length not128/192/256bits. ...
This parameter sets the size of the key the AES-GCM IP is expecting to receive. To set it, run the command: python gcm_config -m MODE where MODE can be one of the following values: 128, 192 or 256. Example: the following command sets the IP to receive keys of size 192-bits. ...

Ours AES processor uses round operation of 64bits unit instead of 128 bits unit's round operation for small area and small power consumption. And it uses on-the-fly key generation method. Also, it supports 192 bits key and 256 bits key as well as 128 bits input key. This enables key ...
