Digital unlocking of secure containers

A method, comprising:

• determining, at a user device, that a container is within proximity of the user device;
• determining, based at least in part on information received at the user device, that the container includes a mechanical locking mechanism that has been activated;
• sending a signal to the container;
• receiving a response from the container, wherein the response comprises a public key and an indication of the user device having been detected;
• determining a private key stored on the user device;
• generating a hash value by executing a cryptographic hash function on at least the private key and the public key;
• determining the hash value matches an expected value, wherein the expected value is based at least in part on a second public key received from a source different than the container;
• determining that the public key is paired with the private key based at least in part on the hash value matching the expected value;
• outputting, based at least in part on the determining that the public key is paired with the private key, first data configured to deactivate the mechanical locking mechanism;
• and
• receiving, at the user device, second data indicating that the mechanical locking mechanism has been deactivated.

A securable container, comprising:

• a mechanical locking mechanism;
• a storage medium storing a private key;
• at least one memory storing computer-executable instructions;
• and
• at least one processor operatively coupled to the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to:
• receive, based on the container being within a proximity of a user device, a signal from the user device that includes a public key;
• execute a cryptographic hash function on the public key and the private key to obtain a hash value;
• determine that the public key is paired with the private key based on the hash value matching an expected value;
• generate, based at least in part on the determination that the public key is paired with the private key, first data;
• deactivate the mechanical locking mechanism using the first data;
• and
• send an indication to the user device that the mechanical locking mechanism has been deactivated.
