Method Summary

Modifier and Type	Method	Description
OxalisCipher	createCipherFromWrappedHexKey(String wrappedSymmetricKeyAsHexString, PrivateKey privateKey)	Creates an instance of OxalisCipher: Decodes the supplied hex string representation of a wrapped key into an array of bytes representation Creates a cipher, which is initialized with a private key Unwraps (decrypts) the secret key represented by an array of bytes into a SecretKey Creates an OxalisCipher using the unwrapped SecretKey
String	getWrappedSymmetricKeyAsString(PublicKey publicKey, OxalisCipher oxalisCipher)	Encrypts the secret key (symmetric key) held inside the OxalisCipher instance using the supplied PublicKey, after which the resulting wrapped secret key is transformed into a hex string suitable for transmission, persistence etc.

Method Detail

createCipherFromWrappedHexKey

public OxalisCipher createCipherFromWrappedHexKey(String wrappedSymmetricKeyAsHexString,
                                                  PrivateKey privateKey)

Creates an instance of OxalisCipher:

1. Decodes the supplied hex string representation of a wrapped key into an array of bytes representation
2. Creates a cipher, which is initialized with a private key
3. Unwraps (decrypts) the secret key represented by an array of bytes into a SecretKey
4. Creates an OxalisCipher using the unwrapped SecretKey

getWrappedSymmetricKeyAsString

public String getWrappedSymmetricKeyAsString(PublicKey publicKey,
                                             OxalisCipher oxalisCipher)

Encrypts the secret key (symmetric key) held inside the OxalisCipher instance using the supplied PublicKey, after which the resulting wrapped secret key is transformed into a hex string suitable for transmission, persistence etc.

Parameters:

publicKey - the public asymmetric key to use for encrypting the secret symmetric key

oxalisCipher - the instance of OxalisCipher in which the secret symmetric key is held.

Returns:
