If no, is there a way to generate a hash of length RAW(8) using DBMS_CRYPTO? The SHA-1 algorithm always generates a 160-bit (20-byte) hash; you cannot vary the size of it. You are seeing 40 bytes because you are usingLENGTHwhich expects the first argument to be a strin...
但是,在进行摘要之前,我们要把registers里的初始值设置为原始message的MAC。你可以将其想象为让SHA1函数从服务器上的函数运行结束的地方继续进行。 攻击者的 MAC = SHA1(extension + padding) <- 覆盖registers初始值 这个攻击有个前提,在传入服务器的哈希函数时,扩展值必须存在于单独的区块中。所以我们的第二步,...

Inside my code I'm generating hashes of URLs, (which are practically of unbounded length). I'm currently using sha1(), which I know has a tiny chance of a collision, but I have up to 255 bytes to store the hash in so feel that I might as well use that available space to lower...
然而,由于哈希函数的特性,它将任意长度的密码转换为固定长度的哈希值,因此无法直接使用validatesLengthOf来验证密码字段的长度。 为了处理密码字段的验证,可以使用其他适合密码安全的验证方法,例如: 使用密码策略:制定密码策略要求用户密码必须包含特定的字符类型(如大写字母、小写字母、数字、特殊字符),并且具有一定的最...
