I hereby claim:

  * I am an admin of https://jakub-zika.cz
  * I am k21 (https://keybase.io/k21) on keybase.
  * I have a public key with fingerprint BE79 3C64 635A D9A2 0336  A4DD 170F FD0D F768 DC47

To do so, I am signing this object:

{
    "body": {
        "key": {
            "eldest_kid": "010110e9722075c2cc2e440cdf7a29c23d7d512841421532c934903f87b87198dca50a",
            "fingerprint": "be793c64635ad9a20336a4dd170ffd0df768dc47",
            "host": "keybase.io",
            "key_id": "170ffd0df768dc47",
            "kid": "010110e9722075c2cc2e440cdf7a29c23d7d512841421532c934903f87b87198dca50a",
            "uid": "d71f238a6b74e3b17302f571e8285519",
            "username": "k21"
        },
        "service": {
            "hostname": "jakub-zika.cz",
            "protocol": "https:"
        },
        "type": "web_service_binding",
        "version": 1
    },
    "ctime": 1454962512,
    "expire_in": 157680000,
    "prev": "ef49723211de5806257a23f41b47ae2d88ab96dfbc93bbb70d00f2b4dd9c2235",
    "seqno": 4,
    "tag": "signature"
}

which yields the signature:
