They differ in the word size; SHA-256 uses 32-bit words where SHA-512 uses 64-bit words. There are also truncated versions of each standard, known as SHA-224, SHA-384, SHA-512/224 and SHA-512/256. These were also designed by the NSA. SHA-3: A hash function formerly called Keccak, chosen in 2012 after a public competition among non-NSA designers ...
[1] [2] [3] Truncated versions of SHA-2, including SHA-384 and SHA-512/256 are not susceptible, [4] nor is the SHA-3 algorithm. [5] HMAC also uses a different construction and so is not vulnerable to length extension attacks. [6] Lastly, just performing Hash(message ‖ secret) is enough to not be affected.

BLAKE2b is faster than MD5, SHA-1, SHA-2, and SHA-3, on 64-bit x86-64 and ARM architectures. [4] BLAKE2 provides better security than SHA-2 and similar to that of SHA-3: immunity to length extension , indifferentiability from a random oracle, etc. [ 6 ]
The sponge construction for hash functions. P i are blocks of the input string, Z i are hashed output blocks.. In cryptography, a sponge function or sponge construction is any of a class of algorithms with finite internal state that take an input bit stream of any length and produce an output bit stream of any desired length.
ISO/IEC 7816-4:2005 [9] is identical to the bit padding scheme, applied to a plain text of N bytes. This means in practice that the first byte is a mandatory byte valued '80' (Hexadecimal) followed, if needed, by 0 to N − 1 bytes set to '00', until the end of the block is reached.
Secure Hash Algorithm (SHA), per FIPS 180-4, using SHA-384 to protect up to TOP SECRET. Diffie-Hellman (DH) Key Exchange, per RFC 3526, minimum 3072-bit modulus to protect up to TOP SECRET RSA for key establishment (NIST SP 800-56B rev 1) and digital signatures (FIPS 186-4), minimum 3072-bit modulus to protect up to TOP SECRET
