PasswordRecipientInfo

public PasswordRecipientInfo(AlgorithmIdentifier keyEncryptionAlgorithm,
                             ASN1OctetString encryptedKey)

PasswordRecipientInfo

public PasswordRecipientInfo(AlgorithmIdentifier keyDerivationAlgorithm,
                             AlgorithmIdentifier keyEncryptionAlgorithm,
                             ASN1OctetString encryptedKey)

Method Detail

getInstance

public static PasswordRecipientInfo getInstance(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.

getVersion

public ASN1Integer getVersion()

getKeyDerivationAlgorithm

public AlgorithmIdentifier getKeyDerivationAlgorithm()

getKeyEncryptionAlgorithm

public AlgorithmIdentifier getKeyEncryptionAlgorithm()

getEncryptedKey

public ASN1OctetString getEncryptedKey()

toASN1Primitive

public ASN1Primitive toASN1Primitive()

Produce an object suitable for an ASN1OutputStream.

Overrides:

toASN1Primitive in class ASN1Object

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

Returns:

a primitive representation of this object.
