Keosd FAQ

How does keosd store key pairs

keosd encrypts key pairs under-the-hood before storing them on a wallet file. Depending on the wallet implementation, say Secure Clave or YubiHSM, a specific cryptographic algorithm will be used. When the standard file system of a UNIX-based OS is used, keosd encrypts key pairs using 256-bit AES in CBC mode.

How to enable the keosd Secure Enclave

To enable the secure enclave feature of keosd, you need to sign a keosd binary with a certificate provided with your Apple Developer Account. Be aware that there might be some constraints imposed by App Store when signing from a console application. Therefore, the signed binaries might need to be resigned every 7 days.
