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
Click the generate button to produce:

About the SHA-256 Hash Generator
This SHA-256 Hash Generator creates a SHA-256 hash from text. Enter a string, message, ID, token, or sample value, and the tool will return a fixed-length SHA-256 digest.
SHA-256 is part of the SHA-2 family of cryptographic hash functions. It produces a 256-bit hash value, commonly displayed as a 64-character hexadecimal string. The same input always produces the same hash, while even a small change in the input creates a very different result.
SHA-256 is a one-way hash function, not encryption. A SHA-256 hash cannot be decrypted back into the original text.
• Features
Fixed-Length Output: Generate a 256-bit SHA-256 digest shown as a 64-character hexadecimal value.
Text Hashing: Create SHA-256 hashes for plain text, strings, messages, IDs, tokens, and test data.
Line-by-Line Processing: Hash multiple lines separately when each input line needs its own SHA-256 result.
Consistent Results: Use the same input to reproduce the same SHA-256 hash for comparison or verification.
Change Detection: Compare hashes to check whether text content has changed.
• Use Cases
Text Fingerprints: Create a compact SHA-256 fingerprint for a string, message, or sample value.
Development Testing: Generate SHA-256 values for applications, APIs, webhooks, examples, and test cases that require a SHA-256 digest.
Content Comparison: Compare SHA-256 hashes to confirm whether two text inputs are identical.
Learning SHA-256: See how a text input becomes a fixed-length hexadecimal hash.
• Notes
Password Storage: Do not use plain SHA-256 directly for password storage. Use a dedicated password-hashing algorithm such as Argon2id, bcrypt, or PBKDF2.
Text vs. File Checksums: This page generates SHA-256 hashes from text input. To verify a file, use a dedicated SHA-256 file checksum tool.
