Method Detail

getInstance

public static GCMParameters getInstance(java.lang.Object obj)

Return an GCMParameters object from the given object.

Accepted inputs: null → null GCMParameters object ASN1Sequence input formats with GCMParameters structure inside

Parameters:

obj - the object we want converted.

Throws:

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

Overrides:

toASN1Primitive in class ASN1Object

Following copied from class: org.bouncycastle.asn1.ASN1Object

Returns:

a primitive representation of this object.
