Zig Requires Chilkat v11.0.0+

Convert PEM to JKS (Java KeyStore)

See more PEM Examples

Converts a PEM containing private key(s) and certificates into a JKS (Java KeyStore) formatted file. Zig

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

    // Load the PEM from a file.
    // If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.

    // by calling LoadPem instead.

    // Convert to a JavaKeyStore object.

    // certificate.  All other keys and/or certificates will be assigned an auto-generated

    // entire JKS file.  This may be different (if desired) than the password for individual private keys
    // contained within the JKS.
