5.2 Text Locking/Unlocking

5.2.1 Lock Text

The lockText method of BayunCore class locks text with default encryption-policy dictated by server settings.

  • Parameters
    • String text - Text to be locked.
    • Callback success - Success block to be executed after text is successfully locked, returns locked text through key "lockedText".
    • Callback failure - Failure block to be executed if locking fails, returns BayunError.

Java
Kotlin
String plainText = "plainText";

// Callbacks for locking text
Handler.Callback success = new Handler.Callback() {
    @Override
    public boolean handleMessage(Message message) {
        String lockedText = message.getData().getString("lockedText", "");
        return false;
    }
}

Handler.Callback failure = new Handler.Callback() {
    @Override
    public boolean handleMessage(Message message) {
        String error = message.getData().getString("BayunError");
        if (error.equalsIgnoreCase(BayunError.ERROR_INTERNET_CONNECTION)) {

        } else if (error.equalsIgnoreCase(BayunError.ERROR_ENCRYPTION_FAILED)) {
        
        } 
        return false;
    }
};

bayunCore.lockText(plainText, success, failure);


val plaintext = "plainText"
val encryptionPolicy = BayunCore.ENCRYPTION_POLICY_COMPANY
val keyGenerationPolicy = BayunCore.KEY_GENERATION_POLICY_ENVELOPE
val groupId = ""

// Callbacks for locking text
val success = Handler.Callback {
    val lockedText = it.data.getString("lockedText", "")
    false
}

val failure = Handler.Callback {
    val error = it.data.getString("BayunError")
    if (error == BayunError.ERROR_INTERNET_CONNECTION) {

    } else if (error == BayunError.ERROR_ENCRYPTION_FAILED) {

    }
    false
}

bayunCore.lockText(plaintext, encryptionPolicy, keyGenerationPolicy, groupId, success, failure)

5.2.2 Lock Text with encryption-policy

The lockText method with encryption-policy as an optional parameter locks text with the encryption key dictated by the policy.

  • Parameters
    • String text - Text to be locked.
    • int encryptionPolicy - BayunEncryptionPolicy determines the key for locking.
    • int keyGenerationPolicy - BayunKeyGenerationPolicy determines the policy to generate the data encryption key.
    • String groupId - GroupId is required if encryptionPolicy is BayunEncryptionPolicyGroup.
    • Callback success - Success block to be executed after text is successfully locked, returns locked text through key "lockedText".
    • Callback failure - Failure block to be executed if locking fails, returns BayunError.

Java
Kotlin
String plaintext = "plainText";
int encryptionPolicy = BayunCore.ENCRYPTION_POLICY_COMPANY;
int keyGenerationPolicy = BayunCore.KEY_GENERATION_POLICY_ENVELOPE;
String groupId = "groupId";

// Callbacks for locking text
Handler.Callback success = new Handler.Callback() {
    @Override
    public boolean handleMessage(Message message) {
        String lockedText = message.getData().getString("lockedText", "");
        return false;
    }
}

Handler.Callback failure = new Handler.Callback() {
    @Override
    public boolean handleMessage(Message message) {
        String error = message.getData().getString("BayunError");
        if (error.equalsIgnoreCase(BayunError.ERROR_INTERNET_CONNECTION)) {
        
        } else if (error.equalsIgnoreCase(BayunError.ERROR_ENCRYPTION_FAILED)) {
        
        } 
        return false;
    }
};

bayunCore.lockText(plaintext, encryptionPolicy, keyGenerationPolicy, groupId, success, failure);


val plaintext = "plainText"
val encryptionPolicy = BayunCore.ENCRYPTION_POLICY_COMPANY
val keyGenerationPolicy = BayunCore.KEY_GENERATION_POLICY_ENVELOPE
val groupId = "groupId"

// Callbacks for locking text
val success = Handler.Callback {
    val lockedText = it.data.getString("lockedText", "")
    false
}

val failure = Handler.Callback {
    val error = it.data.getString("BayunError")
    if (error == BayunError.ERROR_INTERNET_CONNECTION) {

    } else if (error == BayunError.ERROR_ENCRYPTION_FAILED) {

    }
    false
}

bayunCore.lockText(plaintext, encryptionPolicy, keyGenerationPolicy, groupId, success, failure)


Note : If encryption-policy is other than BayunEncryptionPolicyGroup then groupId should be nil.

5.2.3 Unlock Text

The unlockText method of BayunCore class unlocks text.

  • Parameters
    • String text - Text to be unlocked.
    • Callback success - Success block to be executed after text is successfully unlocked, returns unlocked text through key "unlockedText".
    • Callback failure - Failure block to be executed if unlocking fails, returns BayunError.

Java
Kotlin
String lockedText = "lockedText";

// Callbacks for unlocking text
Handler.Callback success = new Handler.Callback() {
    @Override
    public boolean handleMessage(Message message) {
        String unlockedText = message.getData().getString("unlockedText", "");
        return false;
    }
}

Handler.Callback failure = new Handler.Callback() {
    @Override
    public boolean handleMessage(Message message) {
        String error = message.getData().getString("BayunError");
        if (error.equalsIgnoreCase(BayunError.ERROR_INTERNET_CONNECTION)) {

        } else if (error.equalsIgnoreCase(BayunError.ERROR_DECRYPTION_FAILED)) {

        } 
        return false;
    }
};

bayunCore.unlockText(lockedText, success, failure);

val lockedText = "lockedText"

// Callbacks for unlocking text
val success = Handler.Callback {
    val unlockedText = it.data.getString("unlockedText", "")
    false
}

val failure = Handler.Callback {
    val error = it.data.getString("BayunError")
    if (error == BayunError.ERROR_INTERNET_CONNECTION) {

    } else if (error == BayunError.ERROR_DECRYPTION_FAILED) {

    }
    false
}

bayunCore.unlockText(lockedText, success, failure)
