About the PPK to PEM Converter

This converter turns PuTTY .ppk private keys into the PEM and OpenSSH formats that ssh on macOS and Linux, Git, AWS and most SFTP libraries expect, and turns PEM or OpenSSH keys back into a .ppk for PuTTY, WinSCP and FileZilla. It reads PPK versions 2 and 3, including passphrase-protected files, and does every step in your browser without PuTTYgen.

Key Features

PPK to PEM (BEGIN RSA PRIVATE KEY or BEGIN EC PRIVATE KEY), the format PuTTYgen's Export OpenSSH key writes
PPK to the OpenSSH private key format, and to an authorized_keys public key line
PEM or OpenSSH to .ppk version 3 or version 2, with an optional new passphrase
Decrypts passphrase-protected PPK files: Argon2id for version 3, the SHA-1 scheme for version 2
Checks the Private-MAC, so a wrong passphrase or an edited file is reported instead of producing a broken key
RSA, ECDSA (P-256, P-384, P-521) and Ed25519 keys, with the SHA256 fingerprint ssh-keygen -l shows

Use Cases

Use a .ppk from a Windows teammate with ssh on a Mac, where PuTTYgen is not installed
Turn an AWS EC2 or Lightsail .pem key pair into a .ppk for PuTTY or WinSCP on Windows
Fix the PuTTY key format too new error by saving a version 3 key as version 2 for an older WinSCP or FileZilla
Convert a deploy key for a Jenkins, GitHub Actions or Ansible job that only accepts PEM or OpenSSH keys
Remove or change the passphrase on a .ppk file before handing it to an automation account

Supported Formats

PuTTY PPK version 2 and 3 (unencrypted or aes256-cbc)

PEM RSA and EC private keys (PKCS#1, SEC1)

PKCS#8 private keys (BEGIN PRIVATE KEY)

OpenSSH private keys (unencrypted openssh-key-v1)

OpenSSH authorized_keys public keys (output)

How do I convert a PPK file to PEM without PuTTYgen?

Paste the .ppk here and choose PEM. With PuTTY tools installed the command is puttygen key.ppk -O private-openssh -o key.pem, and the reverse is puttygen key.pem -o key.ppk. ssh-keygen and openssl cannot read .ppk files at all. Version 3 files, which PuTTY 0.75 and later write, protect the key with Argon2id, so decrypting one can take a second in the browser. Run chmod 600 key.pem before using the PEM file with ssh, or it refuses to load a private key that other users can read.
