WebbJava和Python的SHA1加密结果不一致，是因为它们使用的加密算法不同。Java使用的是SHA-1，而Python使用的是SHA1。SHA-1和SHA1的区别在于，SHA-1使用的是160位的消息摘要，而SHA1使用的是160位的消息摘要。因此，它们的加密结果是不一样的。 WebbM * (M-1) / 2T = 1. Based on this, the first collision will happen when: M = √2 * √T. where: M = number of elements being hashed. T = total number of hash values in the hash function. This means if √2* √T elements are hashed, then we will see the first collision. Note: T is the total number of possible hash values.
