override this.GetObject : Java.Security.IKey -> Java.Lang.ObjectParameters
- key
- IKey
the key used to unseal the object.
Returns
the original object.
- Attributes
Exceptions
if deserialization fails.
if deserialization fails.
if the algorithm to decrypt the data is not available.
if the specified key cannot be used to decrypt the data.
Remarks
Retrieves the original (encapsulated) object.
This method creates a cipher for the algorithm that had been used in the sealing operation. If the default provider package provides an implementation of that algorithm, an instance of Cipher containing that implementation is used. If the algorithm is not available in the default package, other packages are searched. The Cipher object is initialized for decryption, using the given key and the parameters (if any) that had been used in the sealing operation.
The encapsulated object is unsealed and de-serialized, before it is returned.

Exceptions

if deserialization fails.
if the specified cipher is a block cipher and the length of the serialized data is not a multiple of the ciphers block size.
if the padding of the data does not match the padding scheme.
Remarks
Retrieves the original (encapsulated) object.
The encapsulated object is unsealed (using the given Cipher, assuming that the Cipher is already properly initialized) and de-serialized, before it is returned.

Remarks
Retrieves the original (encapsulated) object.
This method creates a cipher for the algorithm that had been used in the sealing operation, using an implementation of that algorithm from the given provider. The Cipher object is initialized for decryption, using the given key and the parameters (if any) that had been used in the sealing operation.
The encapsulated object is unsealed and de-serialized, before it is returned.
