Hash files and strings, verify checksums, and run integrity checks fast. Use when generating SHA hashes, verifying files, or comparing digest values.

This skill is a small, local hashing utility and appears safe for general use. Before installing, consider: (1) it runs locally and will read any file path you pass it — avoid giving it paths to sensitive files unless you intend to hash them; (2) do not use MD5 or SHA1 for security-critical purposes (they are cryptographically broken for collision resistance); prefer SHA256/SHA512 for integrity checks; (3) the compare implementation is simple string equality (not constant-time), so do not use it to compare secrets or authentication tokens where timing attacks matter; (4) the script depends on standard coreutils (md5sum/sha1sum/sha256sum/sha512sum/stat); ensure these are present on your system. If you need the skill to run autonomously in an agent, remember it will only execute when invoked (always:false), but an agent with file-system access could invoke it on files the agent can read.

Type: OpenClaw Skill Name: hashgen Version: 3.0.0 The HashGen skill is a standard utility for generating and verifying file and string hashes (MD5, SHA1, SHA256, SHA512). The shell script (scripts/script.sh) uses common Linux coreutils and contains no evidence of data exfiltration, network activity, or malicious execution logic.
