Constructor Detail

X509Extensions

public X509Extensions(AbstractX509Extension a_extension)

Creates a new X509Extensions object from a single extension.

Parameters:

a_extension - an AbstractX509Extension

X509Extensions

public X509Extensions(java.util.Vector a_extensions)

Creates a new X509Extensions object that holds all extensions in the given Vector. The extensions must be of the type AbstractX509Extension.

Parameters:

X509Extensions

X509Extensions(org.bouncycastle.asn1.DERSet a_extensions)

Creates an X509Extensions object from a DERTaggedObject. For internal use only.

Parameters:

a_extensions - a DERTaggedObject containing X509 extensions

X509Extensions

X509Extensions(org.bouncycastle.asn1.x509.X509Extensions a_extensions)

Creates an X509Extensions object from a BouncyCastle X509Extensions object. For internal use only.

Parameters:
