WebFirst, SHA-256 is significantly faster (usually) than SHA-512, and is strong enough for the vast majority of uses. Second, you can truncate hash output, as long as you're aware of … 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).
WebApr 4, 2024 · As an input, SHA-1 creates a 160-bit “message direct,” also known as a sha1 hash key (20-byte). This is often shown as a hexadecimal value with a length of 40 characters. SSL, TLS, S/MIME, and a slew of other security protocols and applications utilize this approach. 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.
