Hutool-crypto Overview

Encryption can be divided into three types:

1. Symmetric encryption, such as AES, DES, etc.
2. Asymmetric encryption, such as RSA, DSA, etc.
3. Digest encryption, such as MD5, SHA-1, SHA-256, HMAC, etc.

Hutool-crypto encapsulates these three types of encryption and provides most commonly used encryption algorithms.

For asymmetric encryption, it implements:

• RSA
• DSA

For symmetric encryption, it implements:

• AES
• ARCFOUR
• Blowfish
• DES
• DESede
• RC2
• PBEWithMD5AndDES
• PBEWithSHA1AndDESede
• PBEWithSHA1AndRC2_40

For digest algorithms, it implements:

• MD2
• MD5
• SHA-1
• SHA-256
• SHA-384
• SHA-512
• HmacMD5
• HmacSHA1
• HmacSHA256
• HmacSHA384
• HmacSHA512

Among them, for commonly used algorithms, the module also provides the SecureUtil utility class for quick encryption.
