Why Choose MD5/SHA256 Hash Generator

Generate MD5, SHA-1, SHA-256 and SHA-512 digests of text. Compare exact strings, including whitespace and line breaks, when reproducing a result.

How to Calculate

1Enter the exact text to hash, including any intentional whitespace.
2Read the digest for the algorithm you need; SHA-256 of abc begins ba7816bf8f01cfea.
3Copy the full digest and compare it against a result produced with the same input encoding.

Frequently Asked Questions (FAQ)

Can a hash be decoded?

A hash is not reversible encoding. It maps input to a fixed-length digest. Matching a digest does not reveal the original text.

Should I use MD5 or SHA-1 for new security features?

No. Their collision resistance is broken. SHA-256 and SHA-512 are stronger choices for appropriate hash applications, but plain hashes alone are not suitable password storage.

Why do my digests differ?

A trailing newline, an extra space or a different character encoding changes the bytes being hashed. This text tool uses the library’s UTF-8 text encoding.

Calculation Principles & Mathematical Formula

Hash Algorithm Details:
1. MD5: Outputs a 32-character hexadecimal string representing the 128-bit digest. It is fast but cryptographically broken (vulnerable to collisions).
2. SHA-1: Outputs a 40-character hex string representing the 160-bit digest. Deprecated for high-security applications.
3. SHA-256: Outputs a 64-character hex string representing the 256-bit digest. Currently widely used in web certificates, blockchain, and password security.
4. SHA-512: Outputs a 128-character hex string representing the 512-bit digest. Extremely secure, optimized for 64-bit architectures.
