PasswordRecipientInfo

public PasswordRecipientInfo(org.bouncycastle.asn1.x509.AlgorithmIdentifier keyEncryptionAlgorithm,
                             org.bouncycastle.asn1.ASN1OctetString encryptedKey)

PasswordRecipientInfo

public PasswordRecipientInfo(org.bouncycastle.asn1.x509.AlgorithmIdentifier keyDerivationAlgorithm,
                             org.bouncycastle.asn1.x509.AlgorithmIdentifier keyEncryptionAlgorithm,

Method Detail

getInstance

public static PasswordRecipientInfo getInstance(org.bouncycastle.asn1.ASN1TaggedObject obj,
                                                boolean explicit)

Return a PasswordRecipientInfo object from a tagged object.

Parameters:

obj - the tagged object holding the object we want.

explicit - 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 PasswordRecipientInfo getInstance(java.lang.Object obj)

Return a PasswordRecipientInfo object from the given object.

Accepted inputs:

• null → null
• PasswordRecipientInfo object
• ASN1Sequence input formats with PasswordRecipientInfo structure inside

Parameters:

obj - the object we want converted.

Throws:

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