Class Pbes

Used to provide encryption of data using a password. The encryption is a PBKDF2 cryptographic key derivation function. The underlying encryption algorithm is rc2. Note that all Service installations will be using the same salt.

Syntax

Constructors

Pbes()

Initializes a new instance of the Pbes class.

Declaration

Pbes

Examples

Pbes Pbes;

Methods

encrypt(Byte[],String)

The content in the data array will be encrypted using the supplied password. Since this is working on binary data, you must handle character sets if converting between byte data and strings.

Declaration

Byte[] encrypt(Byte[] data,String password)

Parameters

Type	Name	Description
Byte[]	data	Binary data
String	password	Password

Returns

Type	Description
Byte[]	The returned byte array contains the encrypted data

Examples

Pbes pbes;
Byte[] content = String("Hello world").toByteArray();
Byte[] encrypted = pbes.encrypt(content, "foobar");

decrypt(Byte[],String)

The content in the data array will be decrypted using the supplied password. Since this is working on binary data, you must handle character sets if converting between byte data and strings. Note that this method does not check if the password is the same as used when encrypting. If wrong password is used, you will get something else than the original data back.

Declaration

Byte[] decrypt(Byte[] data,String password)

Parameters

Type	Name	Description
Byte[]	data	Binary data
String	password	Password

Returns

Type	Description
Byte[]	The returned byte array contains the decrypted data.

Examples

Pbes pbes;
Byte[] content = String("Hello world").toByteArray();
Byte[] encrypted = pbes.encrypt(content, "foobar");
Byte[] decrypted = pbes.decrypt(encrypted, "foobar");printLine(String(decrypted));
