Class PortCryptoEngine

java.lang.Object

com.codename1.security.CryptoEngine

com.codename1.security.PortCryptoEngine

public class PortCryptoEngine
extends CryptoEngine

The client's default CryptoEngine: PBKDF2 goes to the port's native derivation (CodenameOneImplementation.pbkdf2(String, byte[], byte[], int, int)), everything else runs in Java, and the asynchronous CryptoBatch calls answer on the EDT. A port with more native kernels subclasses it.

Constructor	Description
PortCryptoEngine(com.codename1.impl.CodenameOneImplementation impl)	Creates the engine over a port.

Method Summary

Modifier and Type	Method	Description
void	deliver(Runnable result)	Runs the callback of an asynchronous CryptoBatch call on the EDT.
byte[]	pbkdf2(String hashAlgorithm, byte[] password, byte[] salt, int iterations, int length)	PBKDF2 (RFC 8018) with HMAC over hashAlgorithm (Hash.SHA256 or Hash.SHA512), or null to use the Java derivation.
boolean	randomBytes(byte[] out)	Fills out with bytes from the platform's CSPRNG, answering false when this engine has no source.

Constructor Details

PortCryptoEngine

public PortCryptoEngine(com.codename1.impl.CodenameOneImplementation impl)

Creates the engine over a port.

Parameters

• impl: the port whose native derivation PBKDF2 uses

Method Details

randomBytes

public boolean randomBytes(byte[] out)

Description copied from class: CryptoEngine

Fills out with bytes from the platform's CSPRNG, answering false when this engine has no source. Every installed engine has one: the client's draws on the port, the backend's on the server runtime.

Overrides:

randomBytes in class CryptoEngine

deliver

public void deliver(Runnable result)

Runs the callback of an asynchronous CryptoBatch call on the EDT.

Overrides:

deliver in class CryptoEngine

pbkdf2

public byte[] pbkdf2(String hashAlgorithm,
 byte[] password,
 byte[] salt,
 int iterations,
 int length)

Description copied from class: CryptoEngine

PBKDF2 (RFC 8018) with HMAC over hashAlgorithm (Hash.SHA256 or Hash.SHA512), or null to use the Java derivation. The arguments are already validated.

Overrides:
