Package org.cryptacular.generator
Class LegacyP12Generator
java.lang.Object
org.cryptacular.generator.AbstractP12Generator
org.cryptacular.generator.LegacyP12Generator
- All Implemented Interfaces:
P12Generator
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.
