RSA Private Numbers into Key

Constructs an RSA private key from its component numbers.

Source library: cryptography

Overview

This node reconstructs an RSA private key from its mathematical components: the two primes (p, q), the private exponent (d), and the public key numbers. This is useful when working with raw key material or when keys need to be transmitted in component form.

Parameters

• public_numbers: A NUMOBJ object containing the public key numbers, obtained from another node.
• var_p: One of the two primes composing the private modulus n.
• var_q: One of the two primes composing the private modulus n.
• private_exponent: The private exponent (d).
• skip_rsa_key_validation: (Optional) A BOOLEAN that, when True, skips RSA key validation. Warning: Disabling this validation is unsafe and may cause OpenSSL to misbehave or crash, potentially dragging ComfyUI down with it. Only enable this if you know exactly what you are doing.

Outputs

• public_key: The reconstructed private key object (KEYOBJ).
• private_numbers: The private key numbers as a NUMOBJ object.

Additional Considerations

• This node is useful for debugging or when working with key components from external sources.
• Always verify the origin of key components before using them in production.
• Skipping RSA key validation is unsafe and should only be done in exceptional circumstances.
