open

Open (decrypt) sealed data

Syntax

Function open(sealed_data As String, open_data, env_key As String, priv_key) As Boolean

Returns True on success or False on failure. If successful the opened data is returned in open_data.

open() opens (decrypts) sealed_data using the private key associated with the key identifier priv_key_id and the envelope key env_key, and fills open_data with the decrypted data. The envelope key is generated when the data are sealed and can only be used by one specific private key. See seal() for more information.

Example

size = crypto.seal("Secret text", sealed_text, passwords, Array("file://public_key.pem")

' After execution, sealed_text will contain an encrypted variable, password will be an array with 1 item. It will contain a password for source text encrypted by RSA public key.

crypto.open (sealed_text,decrypted_text,passwords(0), "file://private_key.pem")
