load key "archivo.key": error in libcrypto

And you’re like: “What is libcrypto and why does it hate me?”

Relax. Here I’ll give you the straight facts, no beating around the bush.

🤔 What does “load key error in libcrypto” mean?

It’s an error that appears when OpenSSL or some tool that depends on its library (like ssh, scp, curl, git, etc.) tries to load a key private, but it can’t do it because:

  • ❌ The file is corrupted
  • 🔒 The key is encrypted and can’t be read without a passphrase
  • 🔑 <a href="https://www.chusmeando.com/informatica-y-tecnologia/aprende-como-convertir-pdf-a-word-sin-perder-el-format-usando-herramientas-como-adobe-acrobat-google-docs-o-smallpdf-descubre-metodos-gratuitos/” title=”How to convert PDF to Word without losing formatting”>The key format isn’t supported
  • 📄 The file doesn’t have the correct permissions
  • 😬 Or simply… you’re pointing to the wrong file

🧠 Quick translation:

“I tried to open this key, but I can’t make sense of it with libcrypto.”

🛠️ How do you fix it?

Here are the basic checks:

  1. Check that the path is correct:
    • "archivo.key" does it actually exist? Is it typed correctly?
    • Protip: use an absolute path if you can.
  2. Check the key format:
    • libcrypto expects keys in PEM format.
    • If yours is .ppk (like PuTTY’s), convert it to .pem: puttygen archivo.ppk -O private-openssh -o archivo.pem
  3. Is the key encrypted?
    • You’ll need the passphrase.
    • Some tools don’t accept encrypted keys (depending on how they’re configured).
  4. Check the file permissions: chmod 600 archivo.key
  5. Convert the key with OpenSSL:
    • If it’s corrupted or badly formatted, you can try converting it: openssl rsa -in archivo.key -out nueva.key

📌 Final tips:

  • Avoid copy/pasting keys from a plain text editor. Sometimes invisible characters sneak in and break everything.
  • If you’re on Windows, watch out for rn when transferring files between systems.
  • To debug, use: ssh -v

🧩 Where does this error usually appear?

  • When doing ssh with a badly generated or incompatible private key.
  • When Git tries to authenticate with a broken key.
  • In automation scripts that load keys through libcrypto.
