Encrypt

Encrypts an object using the specified algorithm and key

Method Signature

Encrypt(object=[any], key=[string], algorithm=[string], encoding=[string], IVorSalt=[any], iterations=[integer], precise=[boolean])

Arguments

Argument	Type	Required	Description	Default
object	any	false	The object to encrypt. If the object is not a string or binary data, the object must implement the java.io.Serializable interface
key	string	true	The string representation of the secret key to use for encryption ( see generateSecretKey() )
algorithm	string	false	The algorithm to use for encryption. Default is AES
encoding	string	false	The encoding type to use for encoding the encrypted data. Default is Base64	UU
IVorSalt	any	false	The initialization vector or salt to use for encryption.
iterations	integer	false	The number of iterations to use for encryption. Default is 1000	1000
precise	boolean	false	If set to true, the string and key will be validated before encryption to ensure conformity to the algorithm. Default is false	true

Examples

Encrypt using AES Encryption in ECB Mode

The key must be generated using the generateSecretKey("AES") function.

Run Example

encrypt( "top secret", "WTq8zYcZfaWVvMncigHqwQ==", "AES", "Base64" );

Result: keciULin7bxOWvN/BOarWw==

Encrypt using AES Cipher Block Chaining (CBC) mode

By default encrypt() uses the Electronic Code Book (ECB) mode for encryption. For increased security you should specify the mode and padding to use. In this example we will use CBC mode and PKCS5Padding. The value of the encrypted string will be different every time it runs because the IV is generated at random.

Run Example

msg = "data to encrypt";
key = generateSecretKey( "AES" );
encMsg = encrypt( msg, key, "AES/CBC/PKCS5Padding", "HEX" );
writeOutput( encMsg );

Encrypt using AES Galois/Counter Mode (GCM)

msg = "data to encrypt";
key = generateSecretKey( "AES" );
encMsg = encrypt( msg, key, "AES/GCM/NoPadding", "Base64" );
writeOutput( encMsg );

Additional Examples

Run Example

key = generateSecretKey( "AES" );
testEncrypt = encrypt( "safeourtree", key, "AES", "base64" );
writeDump( testEncrypt );
