512-bit digest calculation with text, chunked file processing, hash verification, and Hex/Base64 output

Online SHA-512 Hash Calculator

SHA-512 belongs to the SHA-2 family and produces a 512-bit digest, represented by 128 hexadecimal characters. Its longer digest provides a greater security margin and it is generally faster on 64-bit systems, making it suitable for higher-strength hashing and long-term archive verification.

Core Functions

  • Text hashing: Calculate hashes in real time or manually, while displaying character, byte, and newline counts.
  • File hashing: Drag and drop or select files for 4 MB chunked processing with progress information, supporting GB-scale files.
  • Hash verification: Enter an expected hash and compare it with the calculated result. Length mismatches are also indicated.
  • Batch hashing: Enter multiline text to calculate one SHA-512 hash for each line.

Output Formats

Supports Hex and Base64 output, including uppercase/lowercase switching for Hex. Results can be copied as Hex, uppercase Hex, Base64, algorithm plus hash, or JSON. TXT, JSON, and CSV export are supported, together with calculation information such as algorithm, input length, encoding, output format, duration, engine, and chunk size.

Processing and Performance

The tool prefers native browser APIs or WebAssembly and falls back to pure JavaScript for compatibility. Files are processed in chunks to prevent memory usage from growing with file size. On very large files, a compatible fallback engine may be slower.

Error Handling

The tool reports missing files, file read failures, unsupported browser algorithms, and module loading failures. Verification mode prompts for missing values when required.

Use Cases

Suitable for stronger file and data integrity verification, database and backup fingerprints, archive verification, API signature debugging, cross-language comparisons, and comparing different digest lengths.

Privacy and Data Security

All processing is performed locally in the browser. Text and files are never uploaded to or saved on a server. Use bcrypt or Argon2 for password storage.

Online SHA-512 hashing for text and files

SHA-512 also belongs to the SHA-2 family and produces a 512-bit digest represented by 128 hexadecimal characters. It provides higher security strength than SHA-256 and is generally faster on 64-bit systems.
  • Three modes: text hashing, file hashing, and hash verification
  • Real-time text hashing with character, byte, and newline statistics
  • 4 MB chunked streaming for files, supporting GB-scale files with progress information
  • Hex and Base64 output with uppercase/lowercase switching for Hex
  • Multiline batch hashing with the ability to copy all results
