Java uses Apache Commons Codec to implement SHA encryption
Apache Commons Codec is a Java class library that provides implementations of common encoding and decoding algorithms, including BASE64, SHA, MD5, and more. It provides developers with a simple and convenient way to encode and encrypt data.
The Maven coordinates of this class library are as follows:
<dependency>
<groupId>commons-codec</groupId>
<artifactId>commons-codec</artifactId>
<version>1.15</version>
</dependency>
The following is a complete example of using Apache Commons Codec to implement SHA encryption:
import org.apache.commons.codec.digest.DigestUtils;
public class SHAExample {
public static void main(String[] args) {
String input = "Hello World";
//Use SHA1 algorithm for encryption
String sha1 = DigestUtils.sha1Hex(input);
System.out.println("SHA1: " + sha1);
//Encrypt using SHA256 algorithm
String sha256 = DigestUtils.sha256Hex(input);
System.out.println("SHA256: " + sha256);
//Encrypt using SHA512 algorithm
String sha512 = DigestUtils.sha512Hex(input);
System.out.println("SHA512: " + sha512);
}
}
Executing the above code will output the following results:
SHA1: 2ef7bde608ce5404e97d5f042f95f89f1c232871
SHA256: 943a702d06f34599aee1f8da8ef9f7296031d699cc560ca44a5b0344a15ce3a4
SHA512: b7e23ec29af22b0b4e41da31e868d57226121c84e62c0511f85e6390388aaf3e2a5df6b08c7c6fa85904aee241cf7b015461f50b8bbf9bc82f9888e95b6158c3
Summary:
Apache Commons Codec is a very convenient Java class library that provides implementations of many commonly used encoding and encryption algorithms. When using SHA encryption, we can use the static method of the DigestUtils class to encrypt and obtain the encryption results. The use of this class library is simple and clear, and can be used by adding dependencies through Maven coordinates.
