About Text Hasher & Encoder
Generate cryptographic hashes and encode text using popular algorithms including Bcrypt (password hashing), MD5, SHA-1, SHA-256, SHA-384, SHA-512, CRC32, Base64, Base64 URL-safe, Hexadecimal, Binary, URL encoding, ROT13, Morse code, and text reversal. Perfect for password hashing, creating checksums, verifying data integrity, encoding data for web applications, generating unique identifiers, and security applications. All processing happens locally in your browser - your data is never sent to any server.
Cryptographic Hash Algorithms
Bcrypt
Password hashing algorithm with built-in salt. Same input produces different outputs each time. Best for storing passwords securely.
SHA-256
256-bit hash. Part of SHA-2 family. Recommended for security applications.
SHA-384
384-bit hash. Truncated version of SHA-512. Higher security than SHA-256.
SHA-512
512-bit hash. Highest security in SHA-2 family. Best for sensitive applications.
MD5
128-bit hash. Fast but not cryptographically secure. Good for checksums and non-security uses.
SHA-1
160-bit hash. Deprecated for security but still used for checksums and Git commits.
CRC32
32-bit checksum. Fast and efficient for error detection. Not for security.
Text Encodings & Transformations
Base64
Standard Base64 encoding. Perfect for embedding binary data in text formats like JSON or XML.
Base64 URL-Safe
URL-friendly Base64 encoding. Uses - and _ instead of + and / for safe URL transmission.
Hexadecimal
Convert text to hex representation. Commonly used for color codes and byte representation.
Binary
Convert text to binary (1s and 0s). Useful for educational purposes and low-level debugging.
URL Encoding
Encode text for safe URL transmission. Converts special characters to percent-encoded format.
ROT13
Simple letter substitution cipher. Rotates each letter 13 positions in the alphabet.
Reverse Text
Reverse the order of characters. Useful for text transformation puzzles.
Morse Code
Convert text to Morse code. Classic encoding method using dots and dashes.
Common Use Cases
- Data Integrity - Verify files haven't been corrupted using hash checksums
- Password Storage - Store hashed passwords instead of plain text (use salted hashes in production)
- API Development - Encode data in Base64 for JSON transmission
- URL Parameters - Encode special characters for safe URL transmission
- Caching - Generate cache keys based on content hashes
- Debugging - Convert text to hex or binary for low-level analysis
- Text Obfuscation - Use ROT13 or reverse for simple text transformation
Frequently Asked Questions
Which hash algorithm should I use?
For password hashing, use Bcrypt. For general security applications, use SHA-256 or SHA-512. For simple checksums, MD5 or CRC32 are faster options.
What is the difference between hashing and encoding?
Hashing is a one-way process that creates a unique fingerprint of your data (cannot be reversed). Encoding transforms data into a different format but can be decoded back to the original. Use hashes for checksums and security, encodings for data transmission and storage.
Can I use Base64 for passwords?
No! Base64 is an encoding (not encryption) and can be easily reversed. Always use cryptographic hashes like SHA-256 for passwords, never encodings.
Are the hashes generated securely?
Yes, we use the Web Crypto API for secure hash generation. All processing happens locally in your browser - your data never leaves your device.
Why does Bcrypt produce different outputs each time?
Bcrypt includes a random salt in each hash, making the output unique every time. This prevents attackers from using rainbow tables. To verify a password, use bcrypt's compare function, not direct hash comparison.
Can hashes be reversed to get the original text?
No, cryptographic hashes are one-way functions. The original input cannot be derived from the hash output. However, encodings like Base64 can be decoded back to the original.
