I have quite a few keys. The one you probably want is my communication ECC key.

Communication Keys

These keys are for signing daily messages and communicating with me. I have RSA and ECC variants. Use ECC if possible, but you can't with old gpg versions. I also frequently use my yubikey for signing and authentication.

• ECC: D217 3817 C3E4 B155 EA8F FF49 A545 31E0 D321 43ED
• RSA: 3D2B B230 F9FA F0C5 1832 46DD 4FDC 96F1 61E7 BA8A

Identity Keys

These keys are signing-only and kept offline. They sign all of my other keys, and will be used to sign your key, and should be used if you are signing my keys.

• ECC: 923E 5634 1E7B A825 D206 B595 26B0 20F1 4082 EF64
• RSA: 29C4 B36C 105F F328 FF03 801A 25B2 0677 37A3 7605
