Description Property (PasswordVault Class)

The description of the vault.

Syntax

public String getDescription();


public void setDescription(String description);

Default Value

""

Remarks

Use this property to provide a textual description (comment) for the vault. This value is not encrypted even if the vault is.

EntryKey Property (PasswordVault Class)

Provides an encryption key for the current entry.

Syntax

public byte[] getEntryKey();


public void setEntryKey(byte[] entryKey);

Remarks

Use this property to provide the encryption/decryption key for the current entry. This property is typically assigned from the EntryKeyNeeded event handler.

This property is automatically generated when a non-empty password is assigned to the EntryPassword property. This is because all entries, and the vault itself, are always encrypted with cryptographically strong keys, and if the user decides to use a password, it is converted to such key using a secure PBKDF function.

This property is not available at design time.

EntryPassword Property (PasswordVault Class)

Provides an encryption password for the current entry.

Syntax

public String getEntryPassword();


public void setEntryPassword(String entryPassword);

Default Value

""

Remarks

Use this property to provide the encryption/decryption password for the current entry. This property is typically assigned from the EntryKeyNeeded event handler.

See a comment in the EntryKey topic to find out how the passwords are used when encrypting entries.

FIPSMode Property (PasswordVault Class)

Reserved.

Syntax

public boolean isFIPSMode();


public void setFIPSMode(boolean FIPSMode);

Default Value

False

Remarks

This property is reserved for future use.

Key Property (PasswordVault Class)

Provides an encryption key for the vault.

Syntax

public byte[] getKey();


public void setKey(byte[] key);

Remarks

Use this property to provide the 'master' key for the vault file. This property can be assigned from the KeyNeeded event handler.

The content of this property is automatically generated when a non-empty password is assigned to the Password property. This is because the vault file are always encrypted with a cryptographically strong key, and if the user decides to use a password, it is converted to such key using a secure PBKDF function first.

This property is not available at design time.

Password Property (PasswordVault Class)

Provides an encryption password for the vault file.

Syntax

public String getPassword();


public void setPassword(String password);

Default Value

""

Remarks

Use this property to provide the master password for the vault file. This property can be assigned from the KeyNeeded event handler.

See a comment in the Key topic to learn how the passwords are used when encrypting the vault file.

PlatformProtection Property (PasswordVault Class)

Enables platform-based protection of the master key.

Syntax

public boolean isPlatformProtection();


public void setPlatformProtection(boolean platformProtection);

Default Value

False

Remarks

Use this property to enable the platform-based protection for the main encryption key. The platform protection is currently only available on Windows, in the form of DPAPI in unmanaged editions, or ProtectedData in .NET Framework.

Title Property (PasswordVault Class)

The title of the vault.

Syntax

public String getTitle();


public void setTitle(String title);

Default Value

""

Remarks

Use this property to provide a title for your vault storage. This value is not encrypted event if the vault itself is.

AddEntry Method (PasswordVault Class)

Adds an entry to the vault.

Syntax

public void addEntry(String entryName);

Remarks

Use this method to add a new entry to the vault. Use SetEntryValue or SetEntryValueStr to assign a value to the new entry.

ChangeEntryKey Method (PasswordVault Class)

Changes the entry's encryption key.

Syntax

public void changeEntryKey(String entryName, byte[] newKey);

Remarks

Use this method to change the entry's encryption key. This method may invoke the EntryKeyNeeded event to request the existing key if the entry was previously encrypted.

ChangeEntryPassword Method (PasswordVault Class)

Changes the entry's encryption password.

Syntax

public void changeEntryPassword(String entryName, String newPassword);

Remarks

Use this method to change the entry's encryption password. This method may invoke the EntryKeyNeeded event to request the existing key if the entry was previously encrypted.

Note that all entries, and the vault itself, are encrypted with cryptographic keys, rather than passwords. When you change an entry's encryption password, you are implicitly changing its encryption key, which is derived from the password using a cryptographically secure key derivation function.

Close Method (PasswordVault Class)

Closes the vault file.

Syntax

public void close();

Remarks

Use this method to close the vault file.

Config Method (PasswordVault Class)

Sets or retrieves a configuration setting.

Syntax

public String config(String configurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.
