Description
Hash files and strings, verify checksums, and run integrity checks fast. Use when generating SHA hashes, verifying files, or comparing digest values.
README (SKILL.md)
HashGen
Quick hash generator for strings and files. Supports MD5, SHA1, SHA256, SHA512 with auto-detection, comparison, and verification.
Commands
| Command | Description |
|---|---|
hashgen md5 \x3Ctext> |
MD5 hash of text |
hashgen sha1 \x3Ctext> |
SHA1 hash of text |
hashgen sha256 \x3Ctext> |
SHA256 hash of text |
hashgen sha512 \x3Ctext> |
SHA512 hash of text |
hashgen all \x3Ctext> |
Show all hash algorithms for text |
hashgen file \x3Cpath> [algo] |
Hash a file (default: sha256) |
hashgen compare \x3Chash1> \x3Chash2> |
Compare two hashes |
hashgen verify \x3Ctext> \x3Chash> |
Verify text matches hash (auto-detects algorithm) |
hashgen version |

Examples
hashgen md5 "hello world" # → MD5: 5eb63bbbe01...
hashgen sha256 "my secret" # → SHA256: 40e1b17...
hashgen all "test" # → shows MD5, SHA1, SHA256, SHA512
hashgen file /etc/hostname # → SHA256 of file
hashgen file /etc/hostname md5 # → MD5 of file
hashgen compare abc123 abc123 # → ✅ MATCH
hashgen verify "hello" 5d41... # → auto-detects algo, verifies
Requirements
md5sum,sha1sum,sha256sum,sha512sum(standard coreutils)
Usage Guidance
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.
Capability Analysis
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.
Capability Assessment
Purpose & Capability
Name/description match the included script and SKILL.md. The script provides commands to hash text and files (md5/sha1/sha256/sha512), compare and verify digests, and reports file size — all aligned with a hash/checksum utility. Required binaries (coreutils md5sum/sha1sum/sha256sum/sha512sum) are appropriate for the stated functionality.
Instruction Scope
SKILL.md and the script are limited to local hashing operations. The script reads only the text arguments and files explicitly provided by the user (it checks file existence and readability). Note: the compare function uses string equality (not a constant-time comparison), so this tool is unsuitable as an authentication comparator for secrets where timing attacks matter. Also detect_algo only infers algorithm from hash length (no validation of hex characters).
Install Mechanism
No install spec; this is instruction-only plus a small bash script. Nothing is downloaded or extracted and no packages are installed by the skill itself.
Credentials
The skill requests no environment variables, no credentials, and no config paths. The operations are local and do not require secrets or external service access.
Persistence & Privilege
always:false (default) and user-invocable:true. The skill does not request persistent presence or modify other skills or system-wide settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install hashgen - After installation, invoke the skill by name or use
/hashgen - Provide required inputs per the skill's parameter spec and get structured output
