Generate and verify hashes (MD5, SHA variants, CRC32, HMAC, BLAKE2) for strings and files with streaming support and no external dependencies.
--- name: hash-toolkit description: Hash generator and verifier supporting MD5, SHA1, SHA256, SHA512, CRC32, HMAC, and BLAKE2. Hash files, strings, or verify integrity. Pure Python, zero dependencies. GitHub: https://github.com/darbling/clawhub-skills 当用户需要计算哈希值、校验文件完整性、MD5校验、SHA256验证、HMAC签名时触发。 --- # 🔐 Hash Toolkit **Author: Lin Hui** | [GitHub](https://github.com/darbling/clawhub-skills) | MIT License | v1.0.0 Compute and verify hashes for strings, files, and data. Supports MD5, SHA1, SHA256, SHA512, CRC32, HMAC, and BLAKE2. ## ✨ Features - **String hashing** — Hash any text with your choice of algorithm - **File hashing** — Compute hash of any file (streaming for large files) - **Verify** — Compare a hash against expected value (pass/fail) - **Batch** — Hash multiple files at once - **HMAC** — Keyed-hash message authentication codes - **CRC32** — Quick checksums for data integrity - **BLAKE2** — Modern, fast, secure hash algorithm ## 🚀 Usage ``` Calculate the SHA256 hash of the string "hello world" ``` ``` Compute the MD5 hash of the file /path/to/file.zip ``` ``` Verify that the SHA256 hash of download.iso matches abc123def... ``` ``` Generate HMAC-SHA256 signature for "message" with key "secret" ``` ``` Calculate CRC32 checksum for data.bin ``` ## ⚙️ Technical Details - **Runtime**: Python 3.6+ - **Dependencies**: Zero (stdlib only: hashlib, hmac, zlib, binascii) - **Algorithms**: MD5, SHA1, SHA224, SHA256, SHA384, SHA512, BLAKE2b, BLAKE2s, CRC32 - **Large files**: Streaming with 8MB chunks
