Enumerate Private Keys in a PFX

See more PFX/P12 Examples

Demonstrates Pfx.PrivateKeyAt, which copies the private key at a zero-based index into a PrivateKey object. The example enumerates all private keys in the PFX.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

load ./chilkat.dll

set success 0

set pfx [new_CkPfx]

#  The file path is relative to the application's current working directory.  An absolute path
#  may also be used.  Supply the path appropriate to your own environment.
#  The PFX password should come from a secure source rather than being hard-coded.
set password "myPfxPassword"
set success [CkPfx_LoadPfxFile $pfx "qa_data/identity.pfx" $password]
if {$success == 0} then {
    puts [CkPfx_lastErrorText $pfx]
    delete_CkPfx $pfx
    exit
}

#  Enumerate the private keys in the PFX by zero-based index.  Valid indexes are less than
#  NumPrivateKeys.
set numKeys [CkPfx_get_NumPrivateKeys $pfx]
set privKey [new_CkPrivateKey]

for {set i 0} {$i <= [expr $numKeys - 1]} {incr i} {
    set success [CkPfx_PrivateKeyAt $pfx $i $privKey]
    if {$success == 0} then {
        puts [CkPfx_lastErrorText $pfx]
        delete_CkPfx $pfx
        delete_CkPrivateKey $privKey
        exit
    }

    puts "Private key $i: [CkPrivateKey_keyType $privKey] ([CkPrivateKey_get_BitLength $privKey] bits)"
}

delete_CkPfx $pfx
delete_CkPrivateKey $privKey
