Byte a 128
WebApr 11, 2024 · 在Java中,字节数组可以存放负值,这是因为Java的byte类型的取值范围为-128到127之间,而在Python3中,bytes的取值范围为0到256。. Java: -127~128 Python: 0~256. 在某些场景下,比如AES加密时,会用到Key、IV(偏移量)等参数值的定义,在Java中有可能是如下的:. public ... WebLike Tom just said, you can truncate SHA-256 output to 128 bits for integrity, because 128 bits is enough to reasonably avoid collisions. However, hash functions like SHA-256 are not suited for key generation or file authenticity (only integrity). If you want to generate a key, use something like PKBDF2 or scrypt.
