Text Hasher
Generate MD5, SHA-1, and SHA-256 hashes from text.
SHA-1
—SHA-256
—SHA-384
—SHA-512
—使用浏览器原生 Web Crypto API 计算，文本不会上传到任何服务器。哈希是单向不可逆的摘要，无法从结果还原出原文—— 这也是它适合用来处理密码这类敏感信息的原因：即使哈希值泄露，也推不出原始密码。
Overview
This tool computes common hash digests (MD5, SHA-1, SHA-256) from any text input, useful for checksums, cache keys, or verifying data integrity.
How to Use
- Type or paste your text.
- View the generated hashes for each algorithm.
- Copy the digest you need.
Common Use Cases
- Verifying a file or string matches an expected checksum
- Generating a deterministic cache key from input text
- Learning how different hash algorithms produce different digest lengths
FAQ
Is MD5 safe to use for passwords?
No — MD5 and SHA-1 are not suitable for password storage. Use a dedicated password hash like bcrypt instead.
