Usage in Deno
import { type PeerCertificate } from "node:tls";
ca: boolean
true if a Certificate Authority (CA), false otherwise.
raw: Buffer
The DER encoded X.509 certificate data.
The certificate subject.
The certificate issuer, described in the same terms as the subject.
valid_from: string
The date-time the certificate is valid from.
valid_to: string
The date-time the certificate is valid to.
serialNumber: string
The certificate serial number, as a hex string.
fingerprint: string
The SHA-1 digest of the DER encoded certificate.
It is returned as a : separated hexadecimal string.
fingerprint256: string
The SHA-256 digest of the DER encoded certificate.
It is returned as a : separated hexadecimal string.
fingerprint512: string
The SHA-512 digest of the DER encoded certificate.
It is returned as a : separated hexadecimal string.
ext_key_usage: string[]
The extended key usage, a set of OIDs.
subjectaltname: string
A string containing concatenated names for the subject,
an alternative to the subject names.
infoAccess: Dict<string[]>
An array describing the AuthorityInfoAccess, used with OCSP.
bits: number
For RSA keys: The RSA bit size.
For EC keys: The key size in bits.
exponent: string
The RSA exponent, as a string in hexadecimal number notation.
modulus: string
The RSA modulus, as a hexadecimal string.
pubkey: Buffer
The public key.
asn1Curve: string
The ASN.1 name of the OID of the elliptic curve. Well-known curves are identified by an OID. While it is unusual, it is possible that the curve is identified by its mathematical properties, in which case it will not have an OID.
nistCurve: string
The NIST name for the elliptic curve, if it has one (not all well-known curves have been assigned names by NIST).
