Conda渠道与包哈希治理（channels-校验-白名单）最佳实践

实现示例type CondaPkg = { name: string; version: string; sha256: string; channel: string }

const allowChannels = new Set<string>(['https://repo.anaconda.com','https://conda.example.com'])

function hex64(h: string): boolean { return /^[A-Fa-f0-9]{64}$/.test(h) }

function channelAllowed(u: string): boolean { try { const x = new URL(u); return x.protocol === 'https:' && allowChannels.has(x.origin) } catch { return false } }

function semverLike(v: string): boolean { return /^(\d+\.\d+\.\d+)(?:[-A-Za-z0-9_.]+)?$/.test(v) }

function evaluate(list: CondaPkg[]): { ok: boolean; errors: string[] } {

const errors: string[] = []

for (const p of list) {

if (!p.name || !semverLike(p.version)) errors.push(`id:${p.name}`)

if (!hex64(p.sha256)) errors.push(`hash:${p.name}`)

if (!channelAllowed(p.channel)) errors.push(`channel:${p.name}`)

}

return { ok: errors.length === 0, errors }

}

审计与运行治理审计渠道域与包哈希；异常阻断并回退到受控渠道。渠道与版本变更需审批与记录，支持回溯。
