About SHA-256

SHA-256 produces a 256-bit digest, written as 64 hexadecimal characters. The same input always produces the same hash, while even a one-character change yields a completely different output. This page's hash is exactly 64 characters long, as expected for SHA-256.

Security: SHA-256 is secure and part of the SHA-2 family. It is widely used in TLS, digital signatures, and Bitcoin, and is the recommended choice for most modern hashing needs. It is most appropriate for TLS, digital signatures, blockchains, and integrity verification.

Can this hash be reversed?

Hashing is one-way — you cannot mathematically reverse a SHA-256 hash to recover its input. However, precomputed (rainbow) tables can simply look up the hashes of common inputs, so a common dictionary word like "login" should never be used as a password. Strong passwords are long, random, and salted before hashing.

Frequently Asked Questions

What is the SHA-256 hash of "login"?▾

The SHA-256 hash of "login" is 428821350e9691491f616b754cd8315fb86d797ab35d843479e732ef90665324.

Is SHA-256 secure?▾

SHA-256 is secure and part of the SHA-2 family. It is widely used in TLS, digital signatures, and Bitcoin, and is the recommended choice for most modern hashing needs.

How long is a SHA-256 hash?▾

A SHA-256 hash is 256-bit, which is 64 hexadecimal characters long.

Can a SHA-256 hash be reversed?▾

No. SHA-256 is a one-way function, so a hash cannot be mathematically reversed back to its input. However, hashes of common inputs can be looked up in precomputed (rainbow) tables — which is why a common word like "login" should never be used as a password.
