sha512sum

Calculate the SHA512 checksum of a file

$ sha512sum [path/to/file]

$ sha512sum [file1] [file2] [file3]

$ sha512sum [*.iso] > [checksums.sha512]

$ sha512sum -c [checksums.sha512]

$ sha512sum -c --quiet [checksums.sha512]

$ echo -n "[text]" | sha512sum

sha512sum [OPTION]... [FILE]...

sha512sum computes and verifies SHA512 (512-bit) message digests as described in FIPS-180-2. It generates a 128-character hexadecimal hash for file contents, providing strong integrity verification.
With no FILE argument or when FILE is -, sha512sum reads from standard input. Output format is: checksum, space, mode indicator (* for binary, space for text), and filename.
SHA512 provides stronger security than SHA1 or MD5 and is suitable for cryptographic applications. There is no difference between binary and text mode on GNU systems.

-b, --binary

Read in binary mode

Read checksums from FILEs and verify them

Read in text mode (default)

Create a BSD-style checksum output

End each output line with NUL instead of newline

Don't fail for missing files when checking

Don't print OK for each successfully verified file

Don't output anything; use exit status for result

Exit non-zero for improperly formatted checksum lines

Warn about improperly formatted checksum lines

SHA512 produces significantly longer hashes (128 hex characters) compared to SHA256 (64) or SHA1 (40). While more secure, verification may be slower for large numbers of files compared to weaker algorithms.

sha512sum is part of GNU coreutils, written by Ulrich Drepper, Scott Miller, and David Madore. SHA-512 was published by NIST as part of the SHA-2 family in 2001, designed to replace the aging SHA-1 algorithm.
