setAlgorithmMapping	back to summary
public JceKTSKeyTransRecipient setAlgorithmMapping(ASN1ObjectIdentifier algorithm, String algorithmName) Internally algorithm ids are converted into cipher names using a lookup table. For some providers the standard lookup table won't work. Use this method to establish a specific mapping from an algorithm identifier to a specific algorithm. For example: unwrapper.setAlgorithmMapping(PKCSObjectIdentifiers.rsaEncryption, "RSA"); Parameters algorithm:ASN1ObjectIdentifier OID of algorithm in recipient. algorithmName:String JCE algorithm name to use. Returns:JceKTSKeyTransRecipient the current Recipient.

setAlgorithmMapping

back to summary

public JceKTSKeyTransRecipient setAlgorithmMapping(ASN1ObjectIdentifier algorithm, String algorithmName)

Internally algorithm ids are converted into cipher names using a lookup table. For some providers the standard lookup table won't work. Use this method to establish a specific mapping from an algorithm identifier to a specific algorithm.

For example:

    unwrapper.setAlgorithmMapping(PKCSObjectIdentifiers.rsaEncryption, "RSA");

Parameters

algorithm:ASN1ObjectIdentifier: OID of algorithm in recipient.
algorithmName:String: JCE algorithm name to use.

Returns:JceKTSKeyTransRecipient

the current Recipient.

setContentProvider	back to summary
public JceKTSKeyTransRecipient setContentProvider(Provider provider) Set the provider to use for content processing. If providerName is null a "no provider" search will be used to satisfy getInstance calls. Parameters provider:Provider the provider to use. Returns:JceKTSKeyTransRecipient this recipient.

setContentProvider

back to summary

public JceKTSKeyTransRecipient setContentProvider(Provider provider)

Set the provider to use for content processing. If providerName is null a "no provider" search will be used to satisfy getInstance calls.

Parameters

provider:Provider: the provider to use.

Returns:JceKTSKeyTransRecipient

this recipient.

setContentProvider	back to summary
public JceKTSKeyTransRecipient setContentProvider(String providerName) Set the provider to use for content processing. If providerName is null a "no provider" search will be used to satisfy getInstance calls. Parameters providerName:String the name of the provider to use. Returns:JceKTSKeyTransRecipient this recipient.

setContentProvider

back to summary

public JceKTSKeyTransRecipient setContentProvider(String providerName)

Set the provider to use for content processing. If providerName is null a "no provider" search will be used to satisfy getInstance calls.

Parameters

providerName:String: the name of the provider to use.

Returns:JceKTSKeyTransRecipient

this recipient.

setKeySizeValidation	back to summary
public JceKTSKeyTransRecipient 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:boolean true if unwrapped key's should be validated against the content encryption algorithm, false otherwise. Returns:JceKTSKeyTransRecipient this recipient.

setKeySizeValidation

back to summary

public JceKTSKeyTransRecipient 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:boolean: true if unwrapped key's should be validated against the content encryption algorithm, false otherwise.

Returns:JceKTSKeyTransRecipient

this recipient.

setProvider	back to summary
public JceKTSKeyTransRecipient setProvider(Provider provider) Set the provider to use for key recovery and content processing. Parameters provider:Provider provider to use. Returns:JceKTSKeyTransRecipient this recipient.

setProvider

back to summary

public JceKTSKeyTransRecipient setProvider(Provider provider)

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

Parameters
