The keychain provides storage for passwords, encryption keys, certificates, and other small pieces of data. Some of these items are inherently secret, like private keys and passwords, while others are not, such as certificates. After storing data in the keychain, you can be confident that untrusted apps cannot access that data. Further, device backups contain only encrypted versions of the secret data.
Keys vary based on the operations they support. For example, you use public and private key pairs to perform asymmetric encryption, whereas you use symmetric keys to conduct symmetric encryption. Similarly, one key might work for a 1024-bit RSA algorithm, while another might be suitable for a 256-bit elliptic curve algorithm. If you’d like to send push notifications to your iOS users, you will need to upload either an APNs Push Certificate, or an APNs Auth Key. We recommend that you create and upload an APNs Auth Key for the following reasons: No need to re-generate the push certificate every yearOne auth key can be use. https://geneenergy.weebly.com/aliens-colonial-marines-steam-product-key-generator.html.
