Abstract: Described is a technique for securing a private secret key during a software build process for a software development kit (SDK) that includes a code implementation for an application programming interface (API), where the private secret key is for use in signing the payload of an API request for the API. Consistent with examples, a keychain service stores a private secret key. In at least one source code file for a SDK, the source code includes a macro definition, which, upon executing by a compiler, obtains a value for the private secret key. In a programming shell environment, a shell script is executed. Execution of the shell script results in executing a nested script, which queries the keychain service for the private secret key.

Abstract: A method of activating a head-worn device is disclosed. The method includes activating the head-worn device and performing a partial bootup. When an user-input instruction to perform a function is received, it is determined whether or not the user-input instruction is permitted for partial bootup execution. The user-input instruction is executed based on the user-input instruction being permitted for partial bootup execution, and a bootup of the head-work device is completed based on the user-input instruction not being permitted for partial bootup execution. The method may further comprise determining if the user-input instruction requires user authentication in order to be executed, and based on the user-input instruction being partial bootup compatible and not requiring user authentication, executing the user-input instruction.
