csguard

csguard is a command-line interface (CLI) application written in Go for calculating and validating checksums for files and folders. The current version supports the MD5,SHA256, SHA512 and CRC hashing algorithms.

Features

• Calculate MD5, SHA256, SHA512 checksum for files and folders
• Validate checksums against provided values
• Easy-to-use command-line interface

Usage

Calculate Checksum

To calculate the checksum for a file, use the following command:

Available -algorithm values are md5, sha256, sha512 and crc. If none are provided, default will be md5

csguard calculate --algorithm md5 --input-file=path/to/file.txt --output=result.txt

OR

csguard calculate --algorithm sha256 --input-folder=path/to/folder --output=result.txt

If --output is not provided, table format will be shown.

Available format are .json, .txt, .yaml and table.

Validate Checksum

To validate the MD5 checksum for a file, use the following command:

csguard validate --algorithm md5 --input-file=path/to/file.txt --checksum=checksum-value-here --output=result.txt

OR To validate the MD5 checksum for multiple files, use the following command:

csguard validate --algorithm sha256 --checksum-file=path/to/file.txt --output=result.txt

Available format for --checksum-file is .json, .txt, .yaml.

	}
]

Warning: filepath are marshalled to \\ but validate clean up those so no need to worries about \\
