Function raw_encrypt 

pub fn raw_encrypt(
    public_key: &RsaPublicKey,
    data: &[u8],
) -> Result<Vec<u8>, Box<dyn Error>>

Encrypts data using a hybrid RSA + AES-GCM approach with a pre-parsed RSA public key.

This is similar to encrypt but takes an already parsed RsaPublicKey object rather than a PEM-encoded string.

Arguments

• public_key - The RSA public key object
• data - The plaintext data to encrypt

Returns

A serialized EncryptedMessage containing the encrypted data

Errors

Returns an error if:

• The AES encryption fails
• The RSA encryption of the AES key fails
• Serialization fails
