WebApr 29, 2016 · For collision resistance, you have half of the bit size, so for SHA-1, which is 160 bits, you only have 90 bits of collision resistance. For MD5, which is 128 bits, you have a mere 64 bits of collision resistance, which of course is very easy to break. – forest Apr 29, 2016 at 5:56 Add a comment You must log in to answer this question.

WebApr 17, 1995 · SHA-1 sequentially processes blocks of 512 bits when computing the message digest. The following specifies how this padding shall be performed. As a summary, a "1" followed by m "0"s followed by a 64- bit integer are appended to the end of the message to produce a padded message of length 512 * n. WebSHA-0 (the first published version of SHA since then replaced by SHA-1) and SHA-1 produce a message digest of 160 bits, SHA-224 of 224 bits, SHA-256 of 256 bits, SHA-384 of 384 bits, and SHA-512 of 512 bits, respectively. All six functions start by padding the message according to the so-called Merkle-Damgård strengthening technique.

WebSHA-1, SHA-224, SHA-256: Input length is bounded to 2 64 bits. SHA-384, SHA-512, SHA-512/224, SHA-512/256: Input length is bounded to 2 128 bits. These are insanely large sizes (and it seems likely that only the ones for SHA-1, SHA-224, and SHA-256 could practically apply to electromagnetic storage).

In cryptography, SHA-1 (Secure Hash Algorithm 1) is a hash function which takes an input and produces a 160-bit (20-byte) hash value known as a message digest – typically rendered as 40 hexadecimal digits.
