Hi,
I can run all the examples in the book from chapter 1 to chapter 5 without any problem.

But, In chapter 5, the programs like X509V1CreateExample, X509V3CreateExample, and some others gives the following exception.
Can anybody help me?

Ibrahim

Exception in thread "main" java.lang.IllegalArgumentException: Unknown signature type requested
    at org.bouncycastle.x509.X509V1CertificateGenerator.s etSignatureAlgorithm(Unknown Source)
    at chapter6.X509V1CreateExample.generateV1Certificate (X509V1CreateExample.java:30)
    at chapter6.X509V1CreateExample.main(X509V1CreateExam ple.java:43)

Two things worth checking, what version of BC are you using? What is the signature algorithm being requested in your version of the example?

Regards,

David

The code I used is from the website of the book. (X509V1CreateExample)


bc version : 133
signature algorithm: "SHA256WithRSAEncryption"

Thanks David

Hmmm... This is a bit of a guess, but you might have a locale issue - there was a problem reported recently with toUpperCase() in some areas. Try the beta at http://www.bouncycastle.org/betas and let me know how you go.

David,
it worked with the beta bc version.

Thanks...
