Windows Credentials Manager - AutoSplit Larger Secrets

See more Secrets Examples

Secrets stored in the Windows Credentials Manager can be a maximum of 2560 bytes in size. If the content of the secret is too large for the Windows Credential Manager, Chilkat will automatically split the secret into parts and store a shorter JSON manifest. Chilkat2 Perl

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

my $secrets = Chilkat2::Secrets->new;

# The default value of AutoSplit is 1.
# Note: AutoSplit only applies when the secret location is "local_manager"
# and the app is running on the Windows OS.  All other secret locations, such as Apple Keychain,
# AWS Secrets Manager, Azure Key Vault, etc. don't have limitations that are so small.
$secrets->AutoSplit(1);

# On Windows, this is the Windows Credentials Manager
# On MacOS/iOS, it is the Apple Keychain
# (This example is explaining how a secret too large for the Windows Credential Manager
# is automatically compressed and split into parts if needed.)
$secrets->Location('local_manager');

# Specify the name of the secret.
# service and username are required.
# appName and domain are optional.
# Note: The values are arbitrary and can be anything you want.
my $json = Chilkat2::JsonObject->new;
$json->UpdateString('appName', 'AA_MyApp');
$json->UpdateString('service', 'OAuth2');
$json->UpdateString('domain', 'onedrive');
$json->UpdateString('username', 'matt');

# Get the secret to be stored.
my $jsonSecret = Chilkat2::JsonObject->new;
my $success = $jsonSecret->LoadFile('qa_data/tokens/oneDrive.json');
if (!$success) {
    print $jsonSecret->LastErrorText, "\n";
    exit;
}

# Note: The oneDrive.json file we used for testing is 4824 bytes in size,
# which exceeds the maximum size (2560 bytes) allowed by the Windows Credentials Manager.

# When the size is too large, Chilkat will first compress the content of the secret.
# If the compressed size is small enough, then it is stored compressed without splitting.
# Otherwise the compressed data is split

# Your application does not need to know how the secret is stored in the Windows Credentials Manager.
# When fetching the secret, Chilkat automatically decompresses and re-composes from parts.

# Create or update the secret.
$success = $secrets->UpdateSecretJson($json, $jsonSecret);
if (!$success) {
    print $secrets->LastErrorText, "\n";
    exit;
}

# This is the auto-split secret viewed in the Windows Credentials Manager:
# 

# Note: If you delete the auto-split secret by calling Chilkat's DeleteSecret method,
# the parts are automatically deleted.
# Also, if you update the secret, the old parts are automatically deleted and new parts are created.
