常用示例
Calculate SHA224 hash
sha224sum [file]
Check hashes from file
sha224sum -c [checksums.txt]
Calculate for multiple files
sha224sum [file1] [file2]
Read from stdin
echo "[text]" | sha224sum
说明
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.
参数

- Verify checksums from file.
- -b, --binary
- Read in binary mode.
- -t, --text
- Read in text mode.
- --quiet
- Don't print OK for verified files.
