Method Detail

values

public static Encryption.Cipher[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Encryption.Cipher c : Encryption.Cipher.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Encryption.Cipher valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getCipherAlgorithm

public static CipherAlgorithm getCipherAlgorithm(UUID cipherUuid)

Find a cipher that matches this Uuid

Parameters:

cipherUuid - the Uuid

Returns:

a cipher

Throws:

IllegalArgumentException - if the Uuid is not known

getCipherUuid

public UUID getCipherUuid()

Description copied from interface: CipherAlgorithm

Returns the UUID of this algorithm

Specified by:

getCipherUuid in interface CipherAlgorithm

getName

public String getName()

Description copied from interface: CipherAlgorithm

Return the name of this algorithm

Specified by:

getName in interface CipherAlgorithm

getDecryptedInputStream

public InputStream getDecryptedInputStream(InputStream encryptedInputStream,
                                           byte[] key,
                                           byte[] iv)

Description copied from interface: CipherAlgorithm

Create a decrypted stream from the supplied encrypted one

Specified by:

getDecryptedInputStream in interface CipherAlgorithm

Parameters:

encryptedInputStream - an encrypted stream

key - the decryption key

iv - the iv

Returns:

an unencrypted stream

getEncryptedOutputStream

public OutputStream getEncryptedOutputStream(OutputStream decryptedOutputStream,
                                             byte[] key,
                                             byte[] iv)

Description copied from interface: CipherAlgorithm

Create an encrypted stream from the supplied unencrypted one

Specified by:

getEncryptedOutputStream in interface CipherAlgorithm

Parameters:

decryptedOutputStream - an unencrypted stream

key - a key

iv - an iv

Returns:

an encrypted stream
