1. Understanding Text Encryption and Decryption

Encryption is the process of converting readable text (plaintext) into an unreadable format (ciphertext) to prevent unauthorized access.
Decryption is the reverse process, converting ciphertext back into readable plaintext.

1.1 Why Encrypt Text?
• Protect sensitive messages from hackers
• Secure personal information
• Safeguard passwords or credentials
• Maintain privacy in communications
• Comply with data protection standards

1.2 Limitations of Manual Encryption
• Time-consuming and error-prone
• Complex for long messages
• Difficult to reverse without the correct key or algorithm
• Not practical for non-technical users

Online tools solve these problems by automating the process.

2. What Are Text Encrypt & Decrypt Tools?

Text Encrypt & Decrypt Tools allow users to quickly convert plain text into encrypted form and vice versa.

2.1 Types of Encryption
• Simple Substitution Cipher: Replace letters with symbols or numbers.
• Caesar Cipher: Shift letters by a fixed number of positions.
• AES / Advanced Encryption: Strong, modern encryption algorithm for sensitive data.
• Base64 Encoding: Encodes text for web-safe transmission.

2.2 Benefits of Using Online Tools
• Fast and easy encryption and decryption
• No installation required
• Compatible with all devices
• Secure and private
• Free for unlimited use
