Chilkat.Pem

Load, inspect, assemble, export, and convert PEM certificate and key material.

Chilkat.Pem is the Chilkat class for handling PEM-formatted certificate and key material. It can load PEM and PKCS#7 data, add certificates, private keys, public keys, CSRs, and certificate chains, retrieve individual items, remove content, control PKCS#1 vs. PKCS#8 private key output, export PEM with optional encryption and extended attributes, and convert PEM material to PFX or Java KeyStore objects.

Load PEM and PKCS#7

Load PEM-encoded certificates, keys, CSRs, and PKCS#7 certificate data from files, strings, or memory.

Collect certs and keys

Add certificates, private keys, public keys, CSRs, and certificate chains into a single PEM container.

Retrieve individual items

Extract selected certificates, keys, CSRs, or chains for use with Cert, PrivateKey, PublicKey, or related Chilkat classes.

Private-key format control

Choose PKCS#1 or PKCS#8 private-key output depending on the format required by the target system.

Encrypted PEM output

Export private-key material with password-based encryption when PEM data must be stored or transferred securely.

Convert to PFX or JKS

Convert PEM certificates and keys into PFX/P12 or Java KeyStore objects when another platform or API requires those container formats.

Common pattern: Use Pem when certificate and key material is packaged as one or more PEM blocks. Load the PEM, inspect or retrieve the needed items, add or remove entries as needed, then export the result as PEM, PFX/P12, or Java KeyStore data. Use Chilkat.Cert, PrivateKey, and PublicKey when working directly with individual objects.

For an extended overview, see Pem Class Overview.

Object Creation

// npm install @chilkat/react-native react-native-nitro-modules
// (React Native 0.76+ with the New Architecture; then `pod install` for iOS.  The Chilkat
//  native library is downloaded and verified during the native build -- see the package README.)

import { Chilkat, Pem } from '@chilkat/react-native'

// Once per app start, before any other Chilkat call:
Chilkat.unlockBundle('Anything for 30-day trial')   // shorthand for new Global().unlockBundle(..)

const pem = new Pem()
// ... the native object is released when `pem` is garbage collected, or now with pem.dispose()

new Pem()

Creates the underlying native Chilkat object. Pem is a Nitro Module HybridObject: use it from the JavaScript thread only (it cannot be passed to a Worklet or another runtime). Every member is synchronous and blocks the JavaScript thread until Chilkat returns; a method that can take a while also exists as a ...Async twin returning a Promise, which runs the same call on a native worker thread so the UI keeps rendering. While such a call is pending, every other call on this object throws, except abort() and assigning onPercentDone / onProgressInfo.

dispose(): void

Releases the native object immediately instead of waiting for garbage collection (useful for a large BinData or an open socket). Calling it more than once is harmless; any other use of the object afterwards throws. An object with a pending ...Async call cannot be disposed until the promise settles.

Errors

A method that can fail throws a plain Error: a method whose only outcome is success or failure returns void and throws on failure; a method producing a string or an object returns it and throws where Chilkat would have returned null. The error's message is "Class.method(...): reason", where the reason is the last informative line of the object's lastErrorText, which holds the full Chilkat log of the failed call. A ...Async twin rejects its promise with the same Error instead of throwing. Properties never throw, and methods that answer a question (has..., is..., ...) return a plain boolean.

try {
  pem.someMethod(...)
} catch (e) {
  console.log((e as Error).message)   // Pem.someMethod(...): <reason>
  console.log(pem.lastErrorText)   // the full Chilkat log of the failed call
}

// The same call without blocking the JavaScript thread:
try {
  await pem.someMethodAsync(...)
} catch (e) {
  console.log((e as Error).message)   // Pem.someMethodAsync: <reason>
}

Properties

AppendMode

// read/write
appendMode: boolean

Introduced in version 9.5.0.49

When set to true, each of the Load* methods appends to the current contents of this PEM object. When set to false, a Load* method replaces the contents of this PEM object. The default is false.
