Method Detail

get

public static CryptoEnvironment get()

decrypt

public byte[] decrypt(byte[] bytes)
               throws IOException

Decrypt a byte array which was previously encrypted using encrypt. For decryption the default ICryptdec is used.

Parameters:

bytes -

Returns:

The decrypted representation of bytes

Throws:

IOException

decryptEncoded

public String decryptEncoded(String value)
                      throws IOException

Throws:

IOException

decryptEncoded

public String decryptEncoded(String value,
                             ICryptdec cryptdec)
                      throws IOException

Throws:

IOException

decryptRaw

public String decryptRaw(String value)
                  throws IOException

Decrypt a string which was previously encrypted using encrypt. Provided the same salt and passphrase are used for initialization, this method returns the original unencrypted input.

Parameters:

value -

Returns:

The decrypted representation of value

Throws:

IOException

encrypt

public byte[] encrypt(byte[] bytes)
               throws IOException

Encrypt a clear text array of bytes. The result is the plain encrypted byte array.

Parameters:

bytes -

Returns:

The encrypted representation of bytes

Throws:

IOException

encryptEncoded

public String encryptEncoded(char[] value)
                      throws IOException

Throws:

IOException

encryptEncoded

public String encryptEncoded(char[] value,
                             ICryptdec cryptdec)
                      throws IOException

Throws:

IOException

encryptEncoded

public String encryptEncoded(String value)
                      throws IOException

Throws:

IOException

encryptEncoded

public String encryptEncoded(String value,
                             ICryptdec cryptdec)
                      throws IOException

Throws:

IOException

encryptRaw

public String encryptRaw(String value)
                  throws IOException

Encrypt a clear text array of chars. The result is a Base64 encoded string version of the encrypted UTF-8 encoded input bytes.

Parameters:

value -

Returns:

An encrypted, invertible representation of value

Throws:

IOException

getDefaultCryptdecDecrypt

public ICryptdec getDefaultCryptdecDecrypt()

getDefaultCryptdecEncrypt

public ICryptdec getDefaultCryptdecEncrypt()

lookupCryptdec

public ICryptdec lookupCryptdec(String id)

registerCryptdec

public void registerCryptdec(ICryptdec cryptdec)

setDefaultCryptdecDecrypt

public void setDefaultCryptdecDecrypt(ICryptdec defaultCryptdec)

setDefaultCryptdecEncrypt

public void setDefaultCryptdecEncrypt(ICryptdec defaultCryptdec)
