API Documentation

All of these functions will throw an error if something is invalid, except the isValid functions, which will return true or false.

Validate SSL

import { validateSSL } from 'ssl-validator';

await validateSSL(cert, options);

Option	Type	Default	Description
skipDateValidation	Boolean	false	Skip verifying the certificate's and/or bundle's validity period.
key	String		When given, validates that the key and certificate are a pair.
domain	String		When given, verifies the certificate is valid for this domain. e.g. 'github.com'
bundle	String		When given, verifies the certificate bundle and certificate go together.
skipFormatValidation	Boolean	false	When true skip validation the format of the certificate and the key.
password	String		A password that will be given to openssl when verifying the key.

Validate SSL Cert

This function validates that the certificate is an SSL certificate and checks the validity period.

import { validateSSLCert } from 'ssl-validator';

await validateSSLCert(cert, options);

Option	Type	Default	Description
skipDateValidation	Boolean	false	Skip verifying the given certificate's validity period.
skipFormatValidation	Boolean	false	When true, skip validation the format of the certificate.

Validate SSL Key

This function validates that the certificate is an SSL certificate and checks the validity period.

import { validateSSLKey } from 'ssl-validator';

await validateSSLKey(key, options);

Option	Type	Default	Description
password	String		A password that will be given to openssl when verifying the key.
skipFormatValidation	Boolean	false	When true, skip validation the format of the key.

Validate Cert Bundle

This function validates that the certificate and the bundle are certificates, and ensures that the bundle and certificate go together.

import { validateCertBundle } from 'ssl-validator';

await validateCertBundle(cert, bundle, options);

Option	Type	Default	Description
skipDateValidation	Boolean	false	Skip verifying the certificate's and/or bundle's validity period.
key	String		When given, validates that the key and certificate are a pair.
domain	String		When given, verifies the certificate is valid for this domain. e.g. 'github.com'
skipFormatValidation	Boolean	false	When true skip validation the format of the certificate and the key.
password	String		A password that will be given to openssl when verifying the key.

Validate Cert Key Pair

This function validates that the given certificate and key are a matching pair.

import { validateCertKeyPair } from 'ssl-validator';

await validateCertKeyPair(cert, key, options);

Option	Type	Default	Description
skipDateValidation	Boolean	false	Skip verifying the certificate's and/or bundle's validity period.
domain	String		When given, verifies the certificate is valid for this domain. e.g. 'github.com'
bundle	String		When given, verifies the certificate bundle and certificate go together.
skipFormatValidation	Boolean	false	When true skip validation the format of the certificate and the key.
password	String		A password that will be given to openssl when verifying the key.

Validate Cert To Domain

This function validates the given certificate and that it matches the given domain.

import { validateCertToDomain } from 'ssl-validator');

await validateCertToDomain(cert, domain, options);

Option	Type	Default	Description
skipDateValidation	Boolean	false	Skip verifying the certificate's and/or bundle's validity period.
key	String		When given, validates that the key and certificate are a pair.
bundle	String		When given, verifies the certificate bundle and certificate go together.
skipFormatValidation	Boolean	false	When true skip validation the format of the certificate and the key.
password	String		A password that will be given to openssl when verifying the key.

IsValid Functions

Each of the functions listed above (validateSSL, validateSSLCert, etc.) has a counterpart that will not throw any errors but will return true when valid and false when not valid. All arguments and options are listed above are valid.

Original Function Name	Predicate Function Name
validateSSL	isValidSSL
validateSSLCert	isValidSSLCert
validateSSLKey	isValidSSLKey
validateCertBundle	isValidCertBundle
validateCertKeyPair	isValidCertKeyPair
validateCertToDomain	isValidCertToDomain

import { isValidSSL } from 'ssl-validator';

if (!(await isValidSSL(cert))) {
  return { message: 'Sorry, the certificate supplied is not valid.' };
}
