Unable to generate public key from private key

[TheAustinSwamy]

Getting this exception with bouncy castle 1.69. Probably not supported yet.

java.security.spec.InvalidKeySpecException: encoded key spec not recognized: 'buf' must have length 32 with bouncy castle 1.69 version. The work around is to go back to 1.68.

org.bouncycastle bcprov-jdk15on 1.69

Here is a simple test case
