Decrypt

Decrypts a provided encoded encrypted string using the specified algorithm and key

Method Signature

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

Arguments

Argument	Type	Required	Description	Default
string	string	true	The encrypted string to decrypt
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	false

Examples

Encrypt and Decrypt a Secret

Generate an AES 128 bit key and then use it to encrypt and decrypt a secret.

Run Example

ex = {};
ex.KEY = generateSecretKey( "AES" );
ex.SECRET = "top secret";
ex.ENCRYPTED = encrypt( ex.SECRET, ex.KEY, "AES", "Base64" );
ex.DECRYPTED = decrypt( ex.ENCRYPTED, ex.KEY, "AES", "Base64" );
writeDump( ex );

Additional Examples

Run Example

key = generateSecretKey( "BLOWFISH" );
testEncrypt = encrypt( "safe_our_tree", key, "BLOWFISH", "base64" );
testDecrypt = decrypt( testEncrypt, key, "BLOWFISH", "base64" );
writeDump( testDecrypt );
