    Return a RecipientKeyIdentifier object from a tagged object.
    
    Parameters:
    
    ato - the tagged object holding the object we want.
    
    isExplicit - true if the object is meant to be explicitly tagged false otherwise.
    
    Throws:
    
    java.lang.IllegalArgumentException - if the object held by the tagged object cannot be converted.
  - getInstance
```
public static RecipientKeyIdentifier getInstance(java.lang.Object obj)
```
    Return a RecipientKeyIdentifier object from the given object.
    Accepted inputs:
    
    null → null
    RecipientKeyIdentifier object
    ASN1Sequence input formats with RecipientKeyIdentifier structure inside
    Parameters:
    
    obj - the object we want converted.
    
    Throws:
    
    java.lang.IllegalArgumentException - if the object cannot be converted.
