Get-Filehash -path c:\downloads\something.exe -algorithm SHA512 | fl *replace the path with your actual file location. *replace the "SHA512" with SHA1, SHA384, SHA512, MACTripleDES, MD5 or RIPEMD160 algorithms if desired. The "| fl" or format list is pretty important here. Without this final part the SHA512 result is cutoff half way through.
N is 16 for an MD5() value and 20 for a SHA1() value. For SHA2() , N ranges from 28 to 32 depending on the argument specifying the desired bit length of the result. The size penalty for storing the hex string in a CHAR column is at least two times, up to eight times if the value is stored in a column that uses the utf8 character set (where each Sha512 hash reverse lookup decryption Sha512 — Reverse lookup, unhash, and decrypt SHA-512 (512 bit) is part of SHA-2 set of cryptographic hash functions, designed by the U.S. National Security Agency (NSA) and published in 2001 by the NIST as a U.S. Federal Information Processing Standard (FIPS). Jul 30, 2017 · The selection of SHA384 vs SHA512 is more about reducing the number of code point alternatives to negotiate. There seemed to be consensus in favor of SHA2-512 over SHA2-384 for key exchanges. 5. SHA is the common name for a family of cryptographic hash functions.The very first member of that family was described under the name 'SHA' but was soon deprecated after a serious weakness was found in it; a fixed version was published under the name SHA-1 (the weak version is colloquially known as SHA-0). You should also consider SHA512. If you only need to support 64 bit CPUs and most messages are 120 bytes or longer, then SHA512 will be faster than SHA256. If you need to support a mixture of 32 and 64 bit CPUs or if most messages are 55 bytes or shorter, then SHA256 will be faster than SHA512. $\endgroup$ – kasperd Mar 27 '16 at 15:05

SHA-256 vs. SHA-1: Comparison Chart . Summary of SHA-256 verses SHA-1. In a nutshell, SHA-256 is more reliable and secure than SHA-1. SHA-256 belongs to the family of SHA-2 cryptographic hash functions designed by the NSA and is commonly used in Blockchain. SHA1 is a bit faster than MD5, maybe there's been some optimization; BLAKE2b is faster than SHA256 and SHA512; BLAKE2s is the fastest of all functions; Note: BLAKE2b is optimized for 64-bit platforms, like mine and I thought it will be faster than BLAKE2s (optimized for 8- to 32-bit platforms) but that's not the case. I'm not sure why is that
Both SHA1 and SHA512 are hash functions. If you are using them as a cryptographic hash, then perhaps that is good reason to use SHA512; however, there are applications that use these function simply to identify objects. For example, Git uses SHA1 to cheaply distinguish between objects.
