Goal: Emulate a Raspberry Pi with QEMU in order to run the Raspbian O/S (based on Debian Linux).
The current setup is not ideal. For one thing, the maximum RAM allowed using the "versatile-pb" firmware is 256 Mb. In addition, only the most basic peripherals, a keyboard and mouse, are supported.
A number of articles have been written on this topic. Most are outdated, and the few recent ones are missing key information.

| KDBX files, the keepass database files, are layout as follows: | |
| 1) Bytes 0-3: Primary identifier, common across all kdbx versions: | |
| private static $sigByte1=[0x03,0xD9,0xA2,0x9A]; | |
| 2) Bytes 4-7: Secondary identifier. Byte 4 can be used to identify the file version (0x67 is latest, 0x66 is the KeePass 2 pre-release format and 0x55 is KeePass 1) |

| # Zero Strip | |
| # | |
| # A one-liner sed expression to nicely strip leading and trailing 0's from each | |
| # line of piped input. | |
| # | |
| # For example: |
| # sudo apt-get install obfs4proxy obfsproxy tor | |
| # sudo vi /etc/tor/torrc | |
| UseBridges 1 | |
| ClientTransportPlugin obfs3 exec /usr/bin/obfsproxy managed | |
| ClientTransportPlugin obfs4 exec /usr/bin/obfs4proxy managed | |
| # send email to [email protected] with body `get transport obfs4` you can get new bridges. | |

This will only work with OpenPGP v2.0 or newer or with PIV cards. Your existing ssh key has to be in a format that is supported by your opengpg card. For example my the OpenPGP V2.1 Card from FLOSS Shop supports only 2048 bit RSA keys. RSA exponent should be 65537, Putty and old OpenSSH releases use different expnent that for example Yubikey does not support.
Yubikey, Smart Cards, OpenSC and GnuPG are pain in the ass to get working. Those snippets here sould help alleviate pain.
To reset and disable not used modes on Yubikey you need the ykman program
You can install it using those commands
| # install: | |
| # pip3 install python-gnupg | |
| # note - gpg needs to be installed first: | |
| # brew install gpg | |
| # apt install gpg | |
| # you may need to also: | |
| # export GPG_TTY=$(tty) |
