Struct der::SecretDocument

source ·
pub struct SecretDocument(/* private fields */);
Expand description

Secret Document type.

Useful for formats which represent potentially secret data, such as cryptographic keys.

This type provides additional hardening such as ensuring that the contents are zeroized-on-drop, and also using more restrictive file permissions when writing files to disk.

Implementations§
