HashCalc: MD5, SHA, HMAC

HashCalc is a simple and reliable utility to generate, compare, and identify cryptographic hashes and HMACs on your Android device.

You can easily calculate MD5, SHA-1, SHA-256, SHA-512, and SHA-3 hashes, or generate secure HMAC keys for both text input and files. Our optimized engine handles large files (4GB+) safely and efficiently, making it ideal for verifying file integrity, checking downloads, generating message authentication codes, and comparing checksums without slowing down your device.

Features:

• True HMAC Support: Securely generate Hash-based Message Authentication Codes with support for both text and hexadecimal secret keys.

• Comprehensive Support: Generate MD5, SHA-1, SHA-256, SHA-512, SHA3-256, and SHA3-512 hashes.

• Hash Detector: Instantly identify unknown hash types based on their length and format.

• Real-time Comparison: Compare hashes with clear visual feedback (✔/✖) to verify integrity or authenticity.

• Large File Optimization: Processes massive files with a real-time progress bar and "Stay Awake" logic.

• History Log: Automatically saves your last 50 calculations with the option to export a formatted log.

• Instant Hashing: Select any file in your file manager and share it directly to HashCalc for a quick checksum.
