About:
Sha2 is a command-line utility that provides fast and reliable implementations of the SHA-2 family of cryptographic hash functions, including SHA-256, SHA-384, and SHA-512. It allows users to quickly compute hash digests for files or standard input, verifying data integrity and authenticity. The tool is designed for simplicity and performance, making it a valuable asset for developers and system administrators.

Key Features:

Supports SHA-256, SHA-384, and SHA-512 algorithms
Simple command-line interface for hashing files and streams
High-performance C implementation
Standardized output for easy scripting and verification

Use Cases:

Verifying file integrity after download or transfer
Generating checksums for secure data validation
Auditing files for changes in a directory

Alternatives:

openssl – OpenSSL is a comprehensive cryptographic toolkit that includes SHA-2 functions, but it is a much larger and more complex dependency.
coreutils (shasum) – The shasum utility, part of Perl or coreutils, is often pre-installed but may be slower than a dedicated C implementation like Sha2.
