PEM Serialized Private Key Loader

Loads a private key from a PEM-encoded byte string.

Source library: cryptography

Overview

This node loads a private key that has been serialized in PEM (Privacy-Enhanced Mail) format. PEM is a widely used, text-based format for storing cryptographic keys, recognizable by its -----BEGIN and -----END headers. The loaded key can then be used by signing or encryption nodes.

Parameters

• keyfile: The PEM-encoded private key data, as a BYTESLIKE object.
• password: (Optional) The password used to decrypt the key, as a BYTESLIKE object. Required if the key was encrypted during serialization.

Outputs

• loaded_key: The loaded private key object (KEYOBJ), ready for use with signing and decryption nodes.

Additional Considerations

• If the key is encrypted, the password must be provided. The password itself should be transmitted securely.
• This node supports all key types that the cryptography library can load via load_pem_private_key, including RSA, EC, EdDSA, and X25519/X448 keys.
• PEM keys are human-readable and widely interoperable, but they are not encrypted by default. Always encrypt private keys before storing them long-term.
