SHA-256 (secure hash algorithm, FIPS 182-2) is a cryptographic hash function with digest length of 256 bits. It is a keyless hash function; that is, an MDC (Manipulation Detection Code).

SHA-256 Cryptographic Hash Algorithm implemented in SHA-256 Cryptographic Hash Algorithm. A cryptographic hash (sometimes called ‘digest’) is a kind of ‘signature’ for a text or a data file. SHA-256 generates an almost-unique 256-bit (32-byte) signature for a text. See below for the source code.

## Anyhow, although they’re two variations of the same algorithm, they do have some technical differences worth mentioning, though. Breaking Down the Values: SHA1 vs SHA2 SHA-1 is a 160-bit (20 byte) hash that is represented by a 40-digit hexadecimal string of numbers.

tls - Does SSLv3 uses SHA256 as hashing algorithm In extensions. SSL 3.0 properly said (with the caveats explained above) does not define any extension, but it leaves room for them. Precisely, RFC 6101 says in section 5.6.1.2: Forward compatibility note: In the interests of forward compatibility, it is permitted for a client hello message to include extra data after the compression methods.

Hashing Algorithm. Input# x 143. Hash Value. 1,525,381. You can see how hard it would be to determine that the value 1,525,381 came from the multiplication of 10,667 and 143. But if you knew that the multiplier was 143, then it would be very easy to calculate the value 10,667.
