What algorithms are supported?

Supported algorithms include MD5, SHA-1, SHA-256, SHA-512, and CRC32. Tools available: `your_tool_name`.

When using `compute_hash`, provide a `secretKey` to trigger the HMAC construction.

Is the comparison secure?

Yes, `compare_hashes` uses a constant-time algorithm to prevent timing attacks.

More Details Connect to Claude

This MCP server provides tools to compute various hashes (MD5, SHA-1, SHA-256, SHA-512, CRC32), perform secure constant-time comparisons between two hashes, and validate the structural integrity of hash strings. Use compute_hash for generating checksums, compare_hashes for equality checks, and validate_format to ensure a string matches its algorithm's expected length and format.
