How to import your SSL certificate in Flipsnack

Learn how to import a custom SSL certificate in Flipsnack

By default, when you use a custom domain or subdomain with your Flipsnack account, Flipsnack automatically provisions a standard SSL certificate generated by Amazon. However, you might want to use a different certificate type or provisioner. 


There might be different reasons to use a custom certificate: more control over how the connection is secured, consistency, or for branding purposes. You can add custom SSL certificates to your Flipsnack account regardless of your motivation. 

There are a few technical specifications you need to keep in mind before adding your certificate:

- Imported SSL should have 1024-bit RSA, 2048-bit RSA, and Elliptic Prime Curve 256-bit keys only

- You must enter the private key that matches the certificate you are importing.

- The private key must be unencrypted. You cannot import a private key that is protected by a password or a passphrase.

- The private key must be no larger than 5 KB (5,120 bytes).

- If the certificate you are importing is not self-signed, you must enter its certificate chain.

- If a certificate chain is included, the issuer must be the subject of one of the certificates in the chain.

- The certificate, private key, and certificate chain must be PEM-encoded.

- The cryptographic algorithm of an imported certificate must match the algorithm of the signing CA. For example, if the signing CA key type is RSA, then the certificate key type must also be RSA.

- A certificate must be an SSL/TLS X.509 version 3 certificate. It must contain a public key, the fully qualified domain name (FQDN) or IP address for your website, and information about the issuer.

- A certificate can be self-signed by a private key you own or signed by the private key of an issuing CA. You must provide the private key, which may be no larger than 5 KB (5,120 bytes) and must be unencrypted.

- If the certificate is signed by a CA, and you choose to provide the certificate chain, the chain must be PEM–encoded.
