Class RSABuilder

java.lang.Object

cz.d1x.dxcrypto.encryption.crypto.AsymmetricAlgorithmBuilder

cz.d1x.dxcrypto.encryption.crypto.RSABuilder

All Implemented Interfaces:

EncryptionAlgorithmBuilder

public class RSABuilder
extends AsymmetricAlgorithmBuilder

Builder for RSA encryption algorithm with these properties:

• Type of cipher: Asymmetric
• Operation mode: Electronic Codebook (ECB)
• Input padding: OAEP with SHA-256 (MGF1 for masks)

If you don't have key pair, you can generate some via RSAKeysGenerator. Recommended usage:

     BigInteger modulus =
     EncryptionAlgorithm aes = new RSABuilder()
                                    .publicKey("myKeySalt) // optional
                                    .iterations(27) // optional
                                    .build();
 

Note that this builder is mutable but built instances are immutable and thus thread safe. For more information about the implementation, see SymmetricAlgorithm.
