    Parameters

    • pem: string

    Returns boolean

isValidX509CertChain

  • isValidX509CertChain(chain, trusted): boolean

  • Returns whether a certificate chain is valid given a set of trusted certificates. The chain and trusted certificates are PEM-encoded bundles of X.509 certificates.

    Parameters

    • chain: string
    • trusted: string

    Returns boolean
