SHA-256 vs SHA-1 vs MD5
- SHA-256 — 64 char output, 256 bits. Most secure. Recommended for all new applications.
- SHA-1 — 40 char output, 160 bits. Deprecated for security use but still used for checksums.
- MD5 — 32 char output, 128 bits. Fast but not collision-resistant. Not for security use.
Frequently Asked Questions
What is SHA-256?+
SHA-256 is a cryptographic hash function that produces a 64-character hexadecimal hash. It is used for password hashing, file verification and digital signatures.
Is SHA-256 more secure than MD5?+
Yes. SHA-256 is considered secure. MD5 has known vulnerabilities and should not be used for security-sensitive applications.
Is my text stored?+
No. Hashing happens in your browser using the Web Crypto API. Nothing is sent anywhere.
Can hashes be reversed?+
No. Hashing is one-way. You cannot recover the original text from a hash.
