Declaration


		
package com.kryptel.cipher;

public interface IRawBlockCipher {
    void EncryptBlock(byte[] dst, int to, byte[] src, int from) throws Exception;
    void DecryptBlock(byte[] dst, int to, byte[] src, int from) throws Exception;
}


	



	

	
		
Description

	
		

		    This interface allows encrypting or decryping a single block of data.
		    No block chaining is used – these methods simply call the underlying
		    cipher imlementation functions EncryptBasicBlock and DecryptBasicBlock
		    (see Adding a New Cipher).
		

		
		
		
EncryptBlock

		
		
void EncryptBlock(byte[] dst, int to, byte[] src, int from) throws Exception;

		
		

			Encrypt block in src at position
			from and store the encrypted data to
			dst at position to.
			The memory areas src/from and
			dst/to may overlap.
		

		
		
		
DecryptBlock

		
		
void DecryptBlock(byte[] dst, int to, byte[] src, int from) throws Exception;

		
		

			Decrypt block in src at position
			from and store the decrypted data to
			dst at position to.
			The memory areas src/from and
			dst/to may overlap.
