If the CA does not provide each of these files for you and you need to separate them manually into root, intermediate, and server certificate, you can do so in one of two ways: The aliases for the intermediate certificates are used as identifiers, but can be whatever you like as long as each is unique. Always use the alias root when importing the root CA certificate and always use the alias used to generate the csr file when importing the server certificate. Note: You will change the alias and file names based on the alias and file names used when generating the csr. Keytool -import -trustcacerts -alias aliasname -keystore temp.keystore -file cert.file In those cases, import each file into the temporary keystore (root first, than intermediate (s), then server certificate) using the command below and a different alias for each: Some CAs will provide the chain leading up to the server certificate in a separate file. In some cases, the customer can get each of the intermediate certificates and root certificate in separate files from the CA. If the file does not contain the full certificate chain, you may have to import each portion of the certificate manually- from the root certificate to the server certificate. (Windows) or How to import a signed certificate that contains the full chain of trust and private key into DPA - Linux See Data Protection Advisor (DPA): How to import a signed certificate that contains the full chain of trust and private key into DPA - Windows or If the file contains the private key, meaning it ends with - BEGIN RSA PRIVATE KEY- and -END RSA PRIVATE KEY, you may be able to import it directly into apollo.keystore. The private key is contained between the - BEGIN RSA PRIVATE KEY- and -END RSA PRIVATE KEY- statements.Įnsure that the number of certificates contained in the - BEGIN CERTIFICATE- and -END CERTIFICATE- statements matches the number of certificates in the chain (server and intermediate). Each certificate is contained between the - BEGIN CERTIFICATE- and -END CERTIFICATE- statements. You can check to see if the full certificate chain is in one file by opening it in a text editor. cer files and the private key can be in a. The server certificate and intermediate certificate can also be in a separate. key)- can include the server certificate, the intermediate certificate and the private key in a single file. p7c)- which contain only the certificates in the chain, not private keys.Ĭertificates in PEM format (.pem. They can also be in PKCS#7 format (.p7b or. p12)- which can store the server certificate, the intermediate certificate and the private key in a single. Typically those files are PKCS#12 (.pfx or. Some certificate file types will contain the signed server certificate, intermediate certificates, and root certificate in one file.In those cases, it may be possible to import the full chain at one time. Without the full certificate chain, the browser will not be able to validate a secure connection. The chain is used to validate a secure connection (https) to the webserver based on it being issued from a trusted certificate authority. ![]() There may be one or more intermediate certificates in between as well.Īll of the certificates connecting the signed server certificate to the root certificate make up the certificate chain. The "chain of trust", allows the browser to establish a trusted connection by providing the full path from the signed certificate to the root certificate. In order to validate that the website is secure and that the certificate has been signed by a trusted certificate authority, the browser must have access to the the certificate chain. I would like to check if these certificates are trusted: openssl verify -CAfile rootCA.crt -untrusted A.crt partner.crt sm.When importing a signed certificate into the temporary keystore, it is important to import the full certificate chain. Openssl x509 -req -in sm.csr -CA partner.crt -CAkey partner.key -CAcreateserial -out sm.crt -days 365 -sha256 -extfile cert_sm.conf Openssl x509 -req -in partner.csr -CA A.crt -CAkey A.key -CAcreateserial -out partner.crt -days 365 -sha256 -extfile cert_nf ![]() ![]() Openssl req -new -key partner.key -out partner.csr -config csr_nf Openssl x509 -req -in A.csr -CA rootCA.crt -CAkey rootCA.key -CAcreateserial -out A.crt -days 365 -sha256 -extfile nf Openssl req -new -key A.key -out A.csr -config csr.conf I have 4 certificatesin chain rootCA.crt->A.crt->partner.crt->sm.crt created with commands: openssl req -x509 -sha256 -days 356 -nodes -newkey rsa:2048 -subj "/CN=/C=US/L=San Fransisco" -keyout rootCA.key -out rootCA.crt
