Generate RSA Key and return Base64 PKCS8 Private Key

See more RSA Examples

Demonstrates how to generate a new 2048-bit RSA private key and returns the Base64 encoded PKCS8 representation of the private key. DataFlex

Use ChilkatAx-win32.pkg

Procedure Test
    Boolean iSuccess
    Handle hoRsa

    // Generate a 2048-bit key.  Chilkat RSA supports
    // key sizes ranging from 512 bits to 8192 bits.
