Text Encryption

Developer

Encrypt and decrypt text using AES, DES, and TripleDES algorithms. Secure client-side encryption tool.

What is This Tool?

A text encryption tool encrypts and decrypts text using standard algorithms like AES-256-GCM and AES-256-CBC. Enter plaintext and a password to produce ciphertext that can only be decrypted with the same password — useful for protecting sensitive data in transit or storage.

AES (Advanced Encryption Standard) is the gold standard for symmetric encryption, approved by NIST and used worldwide. AES-256-GCM provides both confidentiality and authenticity (authenticated encryption), while AES-256-CBC provides confidentiality only and requires a separate MAC for integrity.

Common Use Cases

Sensitive Data Protection

Encrypt API keys, credentials, and sensitive messages before sharing through insecure channels like email or chat.

Configuration Encryption

Encrypt sensitive config values (database passwords, API secrets) before committing to version control.

Learning Cryptography

Experiment with encryption parameters (algorithms, modes, key derivation) to understand symmetric cryptography concepts.

Data at Rest Protection

Encrypt files and text before storing in databases or cloud storage that may not provide built-in encryption.

Frequently Asked Questions

Is this encryption secure?

Yes. AES-256 is the same standard used by governments and financial institutions. Security depends on password strength — use a long, random password.

What is the difference between GCM and CBC?

GCM (Galois/Counter Mode) provides authenticated encryption — it detects tampering. CBC (Cipher Block Chaining) encrypts but does not detect modifications without an additional MAC.

Can I decrypt without the password?

No. AES encryption with a strong password is computationally infeasible to break. If you lose the password, the data is unrecoverable.
