                                  HashMap<Integer,byte[]> preKeys)

Constructor to create a Bundle Element from decoded byte arrays.

Parameters:

signedPreKeyId - id

signedPreKey - signedPreKey

signedPreKeySig - signedPreKeySignature

identityKey - identityKey

preKeys - HashMap of preKeys

Method Detail

getSignedPreKey

public byte[] getSignedPreKey()

Return the signedPreKey of the OmemoBundleElement.

Returns:

signedPreKey as byte array

getSignedPreKeyId

public int getSignedPreKeyId()

Return the id of the signedPreKey in the bundle.

Returns:

id of signedPreKey

getSignedPreKeySignature

public byte[] getSignedPreKeySignature()

Get the signature of the signedPreKey.

Returns:

signature as byte array

getIdentityKey

public byte[] getIdentityKey()

Return the public identityKey of the bundles owner. This can be used to check the signedPreKeys signature. The fingerprint of this key is, what the user has to verify.

Returns:

getPreKeys

public HashMap<Integer,byte[]> getPreKeys()

Return the HashMap of preKeys in the bundle. The map uses the preKeys ids as key and the preKeys as value.

Returns:

preKeys

getPreKey

public byte[] getPreKey(int id)

Return a single preKey from the map.

Parameters:

id - id of the preKey

Returns:

the preKey
