I am using spring boot security version 2.2.5.RELEASE in that , I am creating a custom password encoder with Argon2PasswordEncoder as my password encoder.

In this when i run, can see following error in the Argon2PasswordEncoder.java where i can see these two imports are missing,

import org.bouncycastle.crypto.generators.Argon2BytesGenerator;
import org.bouncycastle.crypto.params.Argon2Parameters;

Error:

java.lang.NoClassDefFoundError: org/bouncycastle/crypto/params/Argon2Parameters$Builder
    at org.springframework.security.crypto.argon2.Argon2PasswordEncoder.encode(Argon2PasswordEncoder.java:78) ~[spring-security-core-5.2.2.RELEASE.jar:5.2.2.RELEASE]
    at com.custom.CustomPasswordEncoder.encode(CustomPasswordEncoder.java:11)

Please suggest me want to do, am I missing some dependency or its the spring boot version issue. And also how to overcome. Many thanks.

I got the issue. for the version 2.2.5 springboot we need to explicitly add the dependency for Argon2BytesGenerator, Argon2Parameters nt found issue, since its not included in this version.

<dependency>
        <groupId>org.bouncycastle</groupId>
        <artifactId>bcprov-jdk15on</artifactId>
        <version>1.64</version>
</dependency>
