Utility Tally

Hash generator

Generate SHA-256, SHA-1, and SHA-512 hashes

Input text
Enter the text you want to hash
How to use this tool
  1. Enter the text you want to hash in the input field
  2. Click "Generate hashes" to create SHA-256, SHA-1, and SHA-512 hashes
  3. Click the copy button next to any hash to copy it to your clipboard
  4. Use SHA-256 for most applications, SHA-512 for maximum security, SHA-1 only for legacy compatibility
Example

Input:

Hello, World!

SHA-256 output:

dffd6021bb2bd5b0af676290809ec3a53191dd81c7f70a4b28688a362182986f

How the hash generator helps

Use the hash generator to create a deterministic fingerprint for text. Hashes are useful for checksums, examples, lookup keys, deduplication, integrity comparisons, and development testing. A hash is one-way in ordinary use, but it is not the same as encryption and should be chosen carefully for security-sensitive work.

Utility Tally tools are built for quick, practical workflows: prepare the input, review the result, copy or download the output, and move on without creating an account. The guidance below explains how to use this page responsibly, what the result means, and which related tools or guides can help with the next step.

For best results, start with sample or non-sensitive data when you are learning a tool, then move to real work only after you understand the output. If the result will be sent to a client, imported into software, printed, published, or used in a security-related workflow, take an extra minute to verify formatting, totals, links, spelling, privacy, and destination requirements.

How to use it
  1. Paste the text you want to hash.
  2. Choose the hash algorithm supported by the tool.
  3. Generate the hash and copy the result.
  4. Compare the hash with an expected value when checking integrity.
  5. Use modern algorithms for security-related work and avoid treating unsalted hashes as password storage.
How it works

A hash function converts input of any length into a fixed-length output. The same input should always produce the same hash, while a small change in input creates a very different result. Strong hash functions make it impractical to find another input with the same output.

The result should be treated as a working output, not a substitute for professional review where tax, security, accessibility, legal, accounting, or production data requirements apply. Check the destination system, final format, and any local rules before relying on the result.

Practical tips

SHA-256 is a practical default for many integrity and development checks.

SHA-1 is considered weak for collision resistance and should not be used for new security designs.

Hashing is not encryption because it cannot be decoded back to the original value.

Password storage needs specialized password hashing with salts and work factors, not a simple fast hash.
