How to use
1. Enter or paste the text you want to generate a hash for in the input box above.
2. Click the Generate button to create the hash result.
Options
1. Process each line separately: When enabled, each line of input is processed separately, and each line produces its own hash. When disabled, the entire input is processed as one single text value.
2. Ignore blank lines: When enabled, blank lines are skipped and no results are generated for them. This option is usually most useful when processing text line by line.
3. Uppercase result: When enabled, the generated hash is displayed in uppercase letters, for example A-F instead of a-f. The original input text is not changed.
Example
Enter the following content:
123456

About the SHA3-256 Generator
Use this online SHA3-256 hash generator to create a SHA3-256 message digest from text. Paste a string, generate the hash, and copy the 256-bit result, commonly shown as a 64-character hexadecimal value.
SHA3-256 is a cryptographic hash function in the SHA-3 family. It is different from SHA-256, which belongs to the SHA-2 family. Both produce 256-bit hash values, but they are based on different algorithm designs, so the same input will not produce the same result across the two algorithms.
SHA3-256 is one-way hashing, not encryption. A hash can help represent or compare text, but it cannot be decrypted back into the original content. If you need encryption or decryption, use a dedicated encryption tool instead.
• Features
Text Hashing: Generate a SHA3-256 hash from plain text or string input.
Fixed-Length Output: Create a 256-bit SHA3-256 digest displayed as a 64-character hexadecimal string.
Line-by-Line Processing: When enabled, process each non-empty line as a separate input and generate individual hash results.
• Common Uses
Development and Testing: Generate SHA3-256 hash values for sample text, API checks, test data, and documentation.
Data Fingerprints: Create a stable digest for text content so the same input can be compared later.
Basic Integrity Checks: Compare SHA3-256 values to see whether text input has changed.
Compatibility: Use SHA3-256 when a system, specification, or workflow specifically requires a SHA-3 256-bit hash.
Password Storage Note: Do not use a plain SHA3-256 hash by itself for password storage. Use a dedicated password-hashing algorithm designed for passwords.
