rsaEncrypt

Encrypt a short message using RSA encryption.

Syntax

Public Function rsaEncrypt ( _
    lpInput() As Byte, _
    szPublicKeyFile As String, _
    Optional nOptions As Long = 0, _
    Optional szParameters As String = "" _
) As Byte()

Parameters

lpInput

Data to be encrypted.

szPublicKeyFile

Name of the public key file or X.509 certificate, or a string containing the key or certificate in PEM format, or a valid internal public key string.

nOptions

Select one of the following:

PKI_EME_PKCSV1_5 (0 default)
PKI_EME_OAEP

If you have selected PKI_EME_OAEP, then add one of these options to set the hash function for EME-OAEP encoding:

PKI_HASH_SHA1
PKI_HASH_SHA224
PKI_HASH_SHA256
PKI_HASH_SHA384
PKI_HASH_SHA512

and, optionally, add PKI_MGF_MGF1SHA1 to force the MGF hash function to be SHA-1 (default = same as encoding hash function set above).

szParameters

For future use.

Return Value
