Compute and verify SHA-224 checksums
TLDR
Calculate SHA224 hash
$ sha224sum [file]
Check hashes from file$ sha224sum -c [checksums.txt]

Read from stdin$ echo "[text]" | sha224sum
SYNOPSIS
sha224sum [options] [file...]
DESCRIPTION
sha224sum computes and verifies SHA-224 cryptographic hash values, producing a 224-bit (56-character hexadecimal) message digest. It is part of the SHA-2 family of hash functions and operates identically to sha256sum in usage, differing only in output length and the underlying truncation of the hash.
SHA-224 is less commonly used than SHA-256 but provides adequate security for applications where a shorter hash is preferred, such as certain certificate signature schemes. With no FILE argument or when FILE is -, input is read from standard input. In check mode (-c), previously generated checksums are verified against current file contents.
PARAMETERS
-c, --check
Verify checksums from file.-b, --binary
Read in binary mode.-t, --text
Read in text mode.--quiet
Don't print OK for verified files.
