OmemoBundleElement

public OmemoBundleElement(int signedPreKeyId,
 String signedPreKeyB64,
 String signedPreKeySigB64,
 String identityKeyB64,
 Map<Integer,String> preKeysB64)

Constructor to create a Bundle Element from base64 Strings.

Parameters:

signedPreKeyId - id

signedPreKeyB64 - base64 encoded signedPreKey

signedPreKeySigB64 - base64 encoded signedPreKeySignature

identityKeyB64 - base64 encoded identityKey

preKeysB64 - Map of base64 encoded preKeys

OmemoBundleElement

public OmemoBundleElement(int signedPreKeyId,
 byte[] signedPreKey,
 byte[] signedPreKeySig,
 byte[] identityKey,
 Map<Integer,byte[]> preKeys)

Constructor to create a Bundle Element from decoded byte arrays.

Parameters:

signedPreKeyId - id

signedPreKey - signedPreKey

signedPreKeySig - signedPreKeySignature

identityKey - identityKey

preKeys - Map of preKeys

Method Details

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:

public identityKey as byte array

getPreKeys

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

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

Returns:

preKeys Pre-Keys contained in the bundle

getPreKey

public byte[] getPreKey(int id)

Return a single preKey from the map.

Parameters:

id - id of the preKey

Returns:

the preKey
