"OpenSSL" Signing CSR Generated by "keytool"
This chapter provides tutorial notes and example codes on using 'OpenSSL' to act as CA (Certificate Authority). Topics include setting up 'OpenSSL' as CA; using 'keytool' to generate CA private key; using 'keytool' to generate CSR (Certificate Signing Request); using 'OpenSSL' to sign CSR, using 'keytool' to import signed certificate into 'keystore' files.
"OpenSSL" Acting as a CA (Certificate Authority)
"OpenSSL" Generating CA's Private Key
"OpenSSL" Self-Signing CA's Public Key
"keytool" Generating Maria's Private Key
"keytool" Generating Maria's CSR
"OpenSSL" Managing Serial Numbers when Signing CSR
After I published my notes on "OpenSSL" and "keytool", many viewers have asked questions about the compatibility between those two tools. In this chapter, I will test how "OpenSSL" can be used to sign CSR generated by "keytool".
