sets the source of random numbers used when generating keys . if you do not provide one , a system default facility is used . you may wish to provide your own source of random numbers to get a reproducible sequence of keys and signatures , or because you may be able to take advantage of strong sources of randomness/entropy in your environment . concode_field_sep PrivateKey privateKey concode_elem_sep PublicKey publicKey concode_elem_sep KeyPairGenerator keyGen concode_elem_sep SecureRandom prng concode_elem_sep String sigAlg concode_field_sep X509Cert getSelfCert concode_elem_sep X509Key getPublicKey concode_elem_sep PrivateKey getPrivateKey concode_elem_sep X500Signer getSigner concode_elem_sep void generate concode_elem_sep X509Certificate getSelfCertificate concode_elem_sep X509Certificate getSelfCertificate concode_elem_sep PKCS10 getCertRequest
