いつまで経ってもbsky.teamのplcにhandle changeが反映されないので色々やってみました。
|
|
|
|
結論から言うと、`PDS_PLC_ROTATION_KEY_K256_PRIVATE_KEY_HEX`を使用し、`base58`のrotation-keyを作成後に、indigoにある`goat plc`を使用します。
|
|
|
|
1. `goat key generate --type secp256k1`で生成されたキーを分析
|
|
2. そのキーから正しいmulticodecプレフィックスを抽出
|
|
3. PDSのhex keyに同じプレフィックスを適用
|
|
|
|
```sh
|
|
$ go install github.com/bluesky-social/indigo/cmd/goat@latest
|
|
```
|
|
|
|
```sh
|
|
$ goat account login -u syui.syui.ai -p $PASS --pds-host https://syu.is
|
|
|
|
$ goat plc history did:plc:vzsvtbtbnwn22xjqhcu3vd6y
|
|
did:key:zQ3shZj81oA4A9CmUQgYUv97nFdd7m5qNaRMyG16XZixytTmQ
|
|
|
|
$ goat plc update did:plc:vzsvtbtbnwn22xjqhcu3vd6y \
|
|
--handle syui.syui.ai \
|
|
--pds https://syu.is \
|
|
--atproto-key did:key:zQ3shZj81oA4A9CmUQgYUv97nFdd7m5qNaRMyG16XZixytTmQ > plc_operation_syui.json
|
|
|
|
# もしミスった時は前の操作を無効化して再実行
|
|
$ goat plc update did:plc:vzsvtbtbnwn22xjqhcu3vd6y \
|
|
--handle syui.syui.ai \
|
|
--pds https://syu.is \
|
|
--atproto-key did:key:zQ3shZj81oA4A9CmUQgYUv97nFdd7m5qNaRMyG16XZixytTmQ \
|
|
--prev "bafyreifomvmymylntowv2mbyvg5i7wgv375757l574gevcs7qbysbqizk4" > plc_operation_syui_nullify.json
|
|
```
|
|
|
|
```sh
|
|
source base58_env/bin/activate
|
|
|
|
python3 -c "
|
|
import base58
|
|
|
|
# 生成されたsecp256k1キーを分析
|
|
generated_secp256k1 = '${zXXX...}'
|
|
decoded = base58.b58decode(generated_secp256k1[1:]) # 'z'を除く
|
|
|
|
print('Generated secp256k1 key analysis:')
|
|
print(' Total length:', len(decoded))
|
|
print(' Full hex:', decoded.hex())
|
|
|
|
# 32バイトの鍵データを除いたプレフィックスを抽出
|
|
if len(decoded) > 32:
|
|
prefix = decoded[:-32]
|
|
key_data = decoded[-32:]
|
|
print(' Prefix hex:', prefix.hex())
|
|
print(' Prefix length:', len(prefix))
|
|
print(' Key data length:', len(key_data))
|
|
|
|
pds_rotation_hex = '${PDS_PLC_ROTATION_KEY_K256_PRIVATE_KEY_HEX}'
|
|
pds_rotation_bytes = bytes.fromhex(pds_rotation_hex)
|
|
|
|
prefixed_rotation_key = prefix + pds_rotation_bytes
|
|
multibase_rotation_key = 'z' + base58.b58encode(prefixed_rotation_key).decode()
|
|
|
|
print('\\nConverted PDS rotation key:')
|
|
print(' Multibase:', multibase_rotation_key)
|
|
|
|
else:
|
|
print(' No prefix found, key is raw')
|
|
"
|
|
|
|
deactivate
|
|
```
|
|
|
|
```sh
|
|
$ PDS_ROTATION_KEY=zXXX...
|
|
|
|
$ goat plc sign --plc-signing-key "$PDS_ROTATION_KEY" plc_operation_syui.json > plc_signed_syui.json
|
|
$ goat plc submit --did did:plc:vzsvtbtbnwn22xjqhcu3vd6y plc_signed_syui.json
|
|
success
|
|
|
|
$ goat plc history did:plc:vzsvtbtbnwn22xjqhcu3vd6y
|
|
```
|
|
|
|
## 手順をおさらい
|
|
|
|
1. `plc_operation.json`を作成
|
|
2. `plc_operation.json`と`PDS_ROTATION_KEY`を使用し、`plc_signed.json`を作成
|
|
3. `plc_signed.json`を使用し、plcを更新
|
|
|
|
## plcを確認
|
|
|
|
```sh
|
|
did=did:plc:vzsvtbtbnwn22xjqhcu3vd6y
|
|
curl -sL "https://plc.directory/$did"|jq .alsoKnownAs
|
|
curl -sL "https://plc.syu.is/$did"|jq .alsoKnownAs
