Struct PublicKey 

pub struct PublicKey { /* private fields */ }

An Ed25519 public key for verifying license signatures.

This is the key that should be embedded in client applications. It can only verify signatures, not create them.

Example

use rust_license_key::crypto::PublicKey;

// Load from base64 (e.g., embedded in application)
let public_key_base64 = "..."; // Your public key here
// let public_key = PublicKey::from_base64(public_key_base64).unwrap();

Implementations

impl PublicKey

pub fn from_base64(public_key_base64: &str) -> Result<Self>

Creates a public key from a base64-encoded string.

Arguments

• public_key_base64 - The base64-encoded public key (32 bytes when decoded).

pub fn from_bytes(bytes: &[u8]) -> Result<Self>

Creates a public key from raw bytes.

Arguments

• bytes - The raw public key bytes (exactly 32 bytes).

pub fn to_bytes(&self) -> [u8; 32]

Returns the public key as raw bytes.

pub fn to_base64(&self) -> String

Returns the public key as a base64-encoded string.

pub fn verify(&self, data: &[u8], signature_bytes: &[u8]) -> Result<()>

Verifies a signature against the given data.

Arguments

• data - The original data that was signed.
• signature_bytes - The signature to verify (64 bytes).

Returns

Ok(()) if the signature is valid, or an error if verification fails.

pub fn verify_base64(&self, data: &[u8], signature_base64: &str) -> Result<()>

Verifies a base64-encoded signature against the given data.

Arguments

• data - The original data that was signed.
• signature_base64 - The base64-encoded signature.

Returns

Ok(()) if the signature is valid, or an error if verification fails.
