ediSecurities. ExportPublicKey

Exports the public key of the Key Exchange key pair to a file.

Syntax:

• <lretval> = object. ExportPublicKey(<sExportFileName>, [<sKeyContainer>], [<sServiceProvider>], [<lProviderType>])

Parameters:

• sExportFileName - Name of the file to export the public key to.
• sKeyContainer - Name of the key container that contains the public key to export.
• sServiceProvider - Optional.  Cryptographic Service Provider (CSP) of the key container. If none is specified, the default CSP is used.
• lProviderType - Optional.  Cryptographic Service Provider type.  For the list of possible provider types please see Cryptographic Service Provider Type Constants.

Returns

Returns 1 if the operation is successful; otherwise returns 0 if the operation fails..

Remarks

The Cryptographic Service Provider (CSP) key container contains two key pairs:

1. Exchange Key Pair for encrypting.
2. Signature Key Pair for authenticating.

This method exports the public key from the Exchange Key Pair only. The file contains the actual BLOB extracted from the key container by the CSP.

The sServiceProvider and lProviderType specify the CSP that has the key container.  If sServiceProvider and/or lProviderType are not specified, the default CSP database is used, which is specified by DefaultProviderName andServiceProviderType.  The type of database, whether machine key set or user key set, is specified using ediDocument.Option by the constant OptDocument_MachineKeySet.

Example:

Set oSecurities = oEdiDoc.GetSecurities

' Creates a new key container for hypothetical trading partner.
oSecurities.DeleteKeyContainer sKeyContainerName
oSecurities.CreateKeyContainer sKeyContainerName

'Export public key
sPKeyFile = "Recipient.pkey.bin"
oSecurities.ExportPublicKey sPKeyFile, sKeyContainerName
