Method Detail

setProvider

public JceKEKRecipient setProvider(java.security.Provider provider)

Set the provider to use for key recovery and content processing.

Parameters:

provider - provider to use.

Returns:

this recipient.

setProvider

public JceKEKRecipient setProvider(java.lang.String providerName)

Set the provider to use for key recovery and content processing.

Parameters:

providerName - the name of the provider to use.

Returns:

this recipient.

setContentProvider

public JceKEKRecipient setContentProvider(java.security.Provider provider)

Set the provider to use for content processing.

Parameters:

provider - the provider to use.

Set the provider to use for content processing.

Parameters:

providerName - the name of the provider to use.

Returns:

this recipient.

setKeySizeValidation

public JceKEKRecipient setKeySizeValidation(boolean doValidate)

Set validation of retrieved key sizes against the algorithm parameters for the encrypted key where possible - default is off.

This setting will not have any affect if the encryption algorithm in the recipient does not specify a particular key size, or if the unwrapper is a HSM and the byte encoding of the unwrapped secret key is not available.

Parameters:

doValidate - true if unwrapped key's should be validated against the content encryption algorithm, false otherwise.

Returns:

this recipient.
