Field Detail

PKIX_VALIDITY_MODEL

public static final int PKIX_VALIDITY_MODEL

This is the default PKIX validity model. Actually there are two variants of this: The PKIX model and the modified PKIX model. The PKIX model verifies that all involved certificates must have been valid at the current time. The modified PKIX model verifies that all involved certificates were valid at the signing time. Both are indirectly choosen with the PKIXParameters.setDate(java.util.Date) method, so this methods sets the Date when all certificates must have been valid.

CHAIN_VALIDITY_MODEL

public static final int CHAIN_VALIDITY_MODEL

This model uses the following validity model. Each certificate must have been valid at the moment where is was used. That means the end certificate must have been valid at the time the signature was done. The CA certificate which signed the end certificate must have been valid, when the end certificate was signed. The CA (or Root CA) certificate must have been valid, when the CA certificate was signed and so on. So the PKIXParameters.setDate(java.util.Date) method sets the time, when the end certificate must have been valid.

It is used e.g. in the German signature law.

setCertStores

public void setCertStores(java.util.List stores)

Sets the Java CertStore to this extended PKIX parameters.

Overrides:

setCertStores in class PKIXParameters

Throws:

java.lang.ClassCastException - if an element of stores is not a CertStore.

setStores

public void setStores(java.util.List stores)

Sets the Bouncy Castle Stores for finding CRLs, certificates, attribute certificates or cross certificates.

The List is cloned.

Parameters:

getStores()

addStore

public void addStore(Store store)

Adds a Bouncy Castle Store to find CRLs, certificates, attribute certificates or cross certificates.

This method should be used to add local stores, like collection based X.509 stores, if available. Local stores should be considered first, before trying to use additional (remote) locations, because they do not need possible additional network traffic.

If store is null it is ignored.

Parameters:

store - The store to add.

See Also:

getStores()

addAddionalStore

public void addAddionalStore(Store store)

Adds a additional Bouncy Castle Store to find CRLs, certificates, attribute certificates or cross certificates.

You should not use this method. This method is used for adding additional X.509 stores, which are used to add (remote) locations, e.g. LDAP, found during X.509 object processing, e.g. in certificates or CRLs. This method is used in PKIX certification path processing.

If store is null it is ignored.

Parameters:

store - The store to add.
