Jasypt Encryption and Decryption Online

Jasypt (Java Simplified Encryption) is a popular Java library used to encrypt and decrypt sensitive data such as passwords, text, numbers, and configuration values.

This free online Jasypt encryption and decryption tool lets you securely encrypt plain text or decrypt Jasypt-encrypted values without writing any code. It supports both one-way password encryption and two-way encryption using standard PBE algorithms.

Jasypt supports PBEWithMD5AndDES by default, with stronger options like PBEWithMD5AndTripleDES.

We do not store, log any key you enter. This tool is intended for personal and educational use. We suggest not to use online tools to protect real production secrets.

Key Features of Jasypt

• Easy to Use: Jasypt provides a simple and intuitive API, allowing developers to implement encryption and decryption in Java applications without in-depth cryptography knowledge.
• Support for Strong Algorithms: Jasypt supports widely used password-based encryption algorithms such as AES, DES, and Triple DES. For direct algorithm-based encryption, you can also try our AES encryption tool or RSA encryption tool.
• Flexible Configuration: Encryption settings can be configured using Java code or external configuration files, making it easy to manage secret keys and encryption parameters.
• Built-in Security Practices: Jasypt automatically handles secure salt generation and key derivation iterations to strengthen encrypted output.
• Framework Integration: Jasypt integrates seamlessly with popular Java frameworks such as Spring and Spring Boot.

How Jasypt Encryption and Decryption Works

• Encryption: To encrypt data using Jasypt, create an instance of StandardPBEStringEncryptor, configure it with a password, and call the encrypt() method with plain text.

  String password = "your_password";
  String data = "Sensitive information";
  
  StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
  encryptor.setPassword(password);
  
  String encryptedData = encryptor.encrypt(data);
        

• Decryption: To decrypt a value encrypted using Jasypt, use the same password and call the decrypt() method to retrieve the original plain text.

  String password = "your_password";
  String encryptedData = "encrypted_string";
  
  StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
  encryptor.setPassword(password);
  
  String decryptedData = encryptor.decrypt(encryptedData);
        

Advantages of Using Jasypt

• Developer Friendly: Simple APIs reduce implementation complexity.
• Algorithm Flexibility: Supports multiple encryption and password-based encryption techniques.
• Password-Based Security: Uses passphrases for key derivation, avoiding direct key storage.

Limitations of Jasypt

The overall security of Jasypt-encrypted data depends heavily on the strength of the password or secret key used. Always use strong, unique passwords. For file- or image-level encryption, consider tools such as file encryption or image encryption.

Integrating Jasypt with Java Applications

Jasypt can be easily added to Java projects using build tools such as Maven or Gradle. Below is an example Maven dependency configuration:

<dependency>
  <groupId>org.jasypt</groupId>
  <artifactId>jasypt</artifactId>
  <version>1.9.5</version>
</dependency>
