12 dayswireguard: T7246: verify Base64 encoded 32byte boundary on keysChristian Breunig
Not 31 bytes or 33 bytes, but exactly 32. This matters, because 32 does not divide evenly by .75, so there's a padding character and the penultimate character does not include the whole base64 alphabet. Extend the base64 validator with an optional argument to define the length to match of the decrypted Base64 encoded string.

2021-08-31ssh: T3789: add custom validator for base64 encoded CLI dataChristian Poessinger
SSH keys used for remote login are supplied as base64 encoded data on the CLI. The key is not validated, thus an invalid copy/pasted key will render the login useless. This commit adds a custom and re-usable validator which check if the data is properly base64 encoded.
