seal
Seal (encrypt) data
Syntax
Function seal (data As String, sealed_data, env_keys, pub_keys, [Base64NoNL]) As Long
Returns the length of the sealed data on success, or 0
on error. If successful the sealed data is returned in sealed_data,
and the envelope keys in env_keys.
seal() seals (encrypts) data
by using RC4 with a randomly generated secret key. The key is encrypted with
each of the public keys associated with the identifiers in pub_key_ids
and each encrypted key is returned in env_keys.
This means that one can send sealed data to multiple recipients (provided one
has obtained their public keys). Each recipient must receive both the sealed
data and the envelope key that was encrypted with the recipient's public key.
Example
| size = crypto.seal("Secret text", sealed_text,
passwords, Array("file://public_key)
' 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. |
