All Implemented Interfaces:

Serializable

public class UntrustedOmemoIdentityException
extends Exception

Exception that gets thrown when we try to en-/decrypt a message for an untrusted contact. This might either be because the user actively untrusted a device, or we receive a message from a contact which contains an identityKey that differs from the one the user trusted.

UntrustedOmemoIdentityException

public UntrustedOmemoIdentityException(OmemoDevice device,
 OmemoFingerprint fpTrusted,
 OmemoFingerprint fpUntrusted)

Constructor for when we receive a message with an identityKey different from the one we trusted.

Parameters:

device - device which sent the message.

fpTrusted - fingerprint of the identityKey we previously had and trusted.

fpUntrusted - fingerprint of the new key which is untrusted.

UntrustedOmemoIdentityException

public UntrustedOmemoIdentityException(OmemoDevice device,
 OmemoFingerprint untrustedKey)

Constructor for when encryption fails because the user untrusted a recipients device.

Parameters:

device - device the user wants to encrypt for, but which has been marked as untrusted.

untrustedKey - fingerprint of that device.

Method Details

getDevice

public OmemoDevice getDevice()

Return the device which sent the message.

Returns:

omemoDevice.

getTrustedFingerprint

public OmemoFingerprint getTrustedFingerprint()

Return the fingerprint of the key we expected. This might return null in case this exception got thrown during encryption process.

Returns:

the trusted fingerprint.

getUntrustedFingerprint

public OmemoFingerprint getUntrustedFingerprint()

Return the fingerprint of the unexpected untrusted key.

Returns:

the OMEMO fingerprint.

getMessage

public String getMessage()

Overrides:

getMessage in class Throwable
