Key store to keep external app keys

ZYMKEY4
1

hi,

I have my Zymkey4i security module and was successfully configured. Now, in my case I have couple of interface applications running on the pi which uses keys to authenticate to certain services on the cloud. Can you elaborate on the key store feature, “Unique Key slots, user available” specified under zymkey4i feature summary. How this can be used to store the keys and their size limitations etc. I am using python.

Thank you

Hi,

The recommended way to store keys/credential for your apps is to store them as encrypted data ‘blobs’ on your SD card. Use Zymkeys Lock/Unlock functions to encrypt and decrypt your in-the-clear keys/credentials, then store/retrieve as needed. This approach provides maximum flexibility on the content of and quantity of credentials, and provides the full encryption of Zymkey.
