Class LegacyP12Generator

org.cryptacular.generator.AbstractP12Generator

org.cryptacular.generator.LegacyP12Generator

All Implemented Interfaces:

P12Generator

public class LegacyP12Generator
extends AbstractP12Generator

Generates PKCS12 containers using DES3+SHA1 for private keys and 40-bit RC2+SHA1 for encrypted data. These algorithms are considered unsecure by today's standards (2024), but are needed for interoperability in some cases. Importing a keypair into the Mac keychain is a notable use case.
