⚠️ The block above is a placeholder. The real key will be published here once generated and verified by the security team. Until then, please use GitHub Security Advisories (the preferred channel) or unencrypted email to security@openbuddy.dev.

How to import

bash
# Save the block above to a file, then:
gpg --import openbuddy-security.pub

# Verify the fingerprint
gpg --fingerprint 0xOPENBUDDY2026

Key verification

Always verify the fingerprint against multiple sources:

  1. This file in the repo
  2. https://openbuddy.dev/security/pgp.txt
  3. Cross-posted in the #security channel on Discord
  4. The OpenBuddy maintainers' public profiles

If any source disagrees, assume compromise and reach out to the maintainer team directly.

Rotation policy

  • Lifetime: 2 years from creation.
  • Overlap: 3 months before expiry — new key is generated, signed by old key, and both distributed for transition.
  • Compromise: emergency rotation, signed by at least 2 current key holders.
  • Storage: offline (YubiKey + paper backup in two geographic locations).

Reporting an encrypted vulnerability

bash
# 1. Import the key
gpg --import openbuddy-security.pub

# 2. Encrypt your report
gpg --armor --encrypt --recipient security@openbuddy.dev \
    --output vulnerability-report.asc \
    vulnerability-report.md

# 3. Send
#   - Email the .asc file as attachment to security@openbuddy.dev
#   - OR open a GitHub Security Advisory at
#     https://github.com/louloulin/OpenBuddy/security/advisories/new
#     and attach the .asc file

Key holders

The key is held by:

  • @louloulin/security team members (≥ 2 required for signing)

Public list: https://github.com/orgs/louloulin/teams/security

⚠️ 上方块是占位符。 真实 key 生成并经安全团队验证后会发布在这里。在此之前,请用 GitHub Security Advisories(首选渠道)或非加密邮件发到 security@openbuddy.dev。

如何导入

bash
# 把上面的块保存到文件,然后:
gpg --import openbuddy-security.pub

# 验证指纹
gpg --fingerprint 0xOPENBUDDY2026

Key 验证

始终对照多个来源验证指纹:

  1. 仓库本文件
  2. https://openbuddy.dev/security/pgp.txt
  3. Discord #security 频道交叉发布
  4. OpenBuddy 维护者的公开档案

任何来源不一致,假定已泄露,直接联系维护者团队。

轮换策略

  • 生命周期:创建起 2 年
  • 重叠期:过期前 3 个月生成新 key,由旧 key 签名,两把同时分发用于过渡
  • 泄露:紧急轮换,至少 2 位当前 key 持有者签名
  • 存储:离线(YubiKey + 两个地理位置的纸质备份)

上报加密漏洞

bash
# 1. 导入 key
gpg --import openbuddy-security.pub

# 2. 加密报告
gpg --armor --encrypt --recipient security@openbuddy.dev \
    --output vulnerability-report.asc \
    vulnerability-report.md

# 3. 发送
#   - 把 .asc 作为附件发到 security@openbuddy.dev
#   - 或开 GitHub Security Advisory:
#     https://github.com/louloulin/OpenBuddy/security/advisories/new
#     并附加 .asc 文件

Key 持有者

key 由:

  • @louloulin/security 团队成员持有(签名需 ≥ 2 人)

公开名单:https://github.com/orgs/louloulin/teams/security

When in doubt, verify the fingerprint. / 拿不准时,验证指纹。
