About:
md5sha1sum is a command-line utility that computes MD5 and SHA1 checksums for files. It provides a unified interface for verifying file integrity and authenticity across different hashing algorithms. The tool is particularly useful for system administrators and developers who need to validate file transfers and ensure data consistency.
Key Features:
  • Computes both MD5 and SHA1 checksums simultaneously
  • Simple command-line interface with consistent output format
  • Supports batch processing of multiple files
  • Cross-platform compatibility
Use Cases:
  • Verifying downloaded files against official checksums
  • Validating file integrity after network transfers
  • Auditing file changes in system directories
  • Comparing checksums between source and destination files
Alternatives:
  • shasum – Built-in macOS/Linux tool supporting multiple SHA algorithms but not MD5
  • md5sum – Standard GNU tool for MD5 only, lacks unified interface
  • openssl – More complex but supports many more hash algorithms
