Strategy Pattern and context class

Reading about the strategy design pattern, was thinking if it is possible to have two context.

Looking forward for opinions if the below code-design utilises the Strategy design pattern.

Or strategy design pattern forces us to have only one context meaning that the design below is incorrect.

public interface Algorithm {}
public class FirstAlgorithm implements Algorithm {}
public class SecondAlgorithm implements Algorithm {}


public interface Cryptography {}

public class DecryptionContext implements Cryptography {
    public DecryptionContext(Algorithm algorithm) {
        this.algorithm = algorithm;
    }
}

public class EncryptionContext implements Cryptography {
public EncryptionContext(Algorithm algorithm) {
        this.algorithm = algorithm;
    }

}
