Method Detail

getInstance

public static SignerIdentifier getInstance(java.lang.Object o)

Return a SignerIdentifier object from the given object.

Accepted inputs:

• null → null
• SignerIdentifier object
• IssuerAndSerialNumber object
• ASN1OctetString input formats with SignerIdentifier structure inside
• ASN1Primitive for SignerIdentifier constructor.

Parameters:

o - the object we want converted.

Throws:

java.lang.IllegalArgumentException - if the object cannot be converted.
