Suporte do Google App Engine para certificados SSL, citação de artigo
App Engine supports the following certificate types:
- Single Domain/Hostname
- Self-signed
- Wildcard
- Subject Alternative Name (SAN) / Multi Domain
It requires some things of your certificates and keys:
- Private Key and Certificate should be uploaded in PEM format.
- Private Keys must not be encrypted.
- A certificate file can contain at most five certificates; this number includes chained and intermediate certificates.
- All subject names on the host certificate should match or be subdomains of the user's verified domains.
- Private keys must use RSA encryption.
- Maximum allowed key modulus: 2048 bits
If the host certificate requires an intermediate or chained certificate (as many Certificate Authorities (CAs) issue), you will need to append the intermediate or chained certificates to the end of the public certificate file.
Some App Engine features use special subdomains. For example, an application can use subdomains to address application services, or to address different versions of your application. To use these with SSL, it makes sense to set up a SAN or wildcard certificate. Wildcard certificates only support one level of subdomain.
