I hereby claim:

  * I am an admin of https://wchmurach.com.pl
  * I am xcmats (https://keybase.io/xcmats) on keybase.
  * I have a public key with fingerprint B9C1 D326 7B64 5F3F 6C45  85B5 CBFF 8A9B 9B57 08F5

To do so, I am signing this object:

{
  "body": {
    "key": {
      "eldest_kid": "0101c21438035377f5f29a2c10382f78bf593212e3d2f1cb3fa18ea940c370f232bc0a",
      "fingerprint": "b9c1d3267b645f3f6c4585b5cbff8a9b9b5708f5",
      "host": "keybase.io",
      "key_id": "cbff8a9b9b5708f5",
      "kid": "0101c21438035377f5f29a2c10382f78bf593212e3d2f1cb3fa18ea940c370f232bc0a",
      "uid": "83b43766d98cbc70ddae5ee6d50bb919",
      "username": "xcmats"
    },
    "service": {
      "hostname": "wchmurach.com.pl",
      "protocol": "https:"
    },
    "type": "web_service_binding",
    "version": 1
  },
  "ctime": 1553109305,
  "expire_in": 157680000,
  "prev": "ca0c91482d141a60c0aa17057034d81e2883f1802e044efd91f21d71f438beb6",
  "seqno": 20,
  "tag": "signature"
}

which yields the signature:
