secure_token_tokenize_segments
The 'secure_token_tokenize_segments' directive enables or disables token generation for specified segments in a CDN URI.
Description
The 'secure_token_tokenize_segments' directive is part of the Secure Token Module in NGINX, which facilitates the generation of secure tokens for streaming media segments, particularly in conjunction with CDN technologies. By setting this directive to 'on', you can instruct NGINX to tokenize specific segments of the application, which increases security by ensuring that segment access is controlled through time-limited tokens. This is particularly useful when delivering dynamic content through CDNs like Akamai or Amazon CloudFront, giving users temporary access to resources that would otherwise be publicly accessible.
When implementing this directive, one must specify it in the appropriate contexts: http, server, or location, allowing the flexibility to apply its scope at various levels of the server configuration. The flag argument means that you simply turn tokenization on or off; specifying 'on' enables the functionality, while 'off' disables it. This morphological choice allows administrators to fine-tune security measures based on their content delivery requirements and user expectations.
Config Example
server {
location /media/ {
secure_token_tokenize_segments on;
secure_token key=my_secret_key;
}
}Ensure your CDN supports tokenized segments, as not all configurations may apply universally.
Be cautious about the performance impact of tokenization, especially for high-throughput applications.
Token expiration times must be configured correctly to prevent access issues.
