Struct ProfilePublicKeyData 

pub struct ProfilePublicKeyData {
    pub expires_at: SystemTime,
    pub key: RsaPublicKey,
    pub key_signature: Vec<u8>,
}

Profile public key data containing key, expiry, and Mojang signature.

Equivalent to ProfilePublicKey.Data in Minecraft.

Fields

expires_at: SystemTime

When this key expires

key: RsaPublicKey

The RSA public key

key_signature: Vec<u8>

Signature of this key signed by Mojang’s services

Implementations

impl ProfilePublicKeyData

pub const fn new( expires_at: SystemTime, key: RsaPublicKey, key_signature: Vec<u8>, ) -> Self

Creates new profile public key data

pub fn has_expired(&self) -> bool

Checks if the key has expired (without grace period)

pub fn has_expired_with_grace(&self, grace_period: Duration) -> bool

Checks if the key has expired, with a grace period

pub fn validate_signature( &self, profile_id: Uuid, validator: &dyn SignatureValidator, ) -> Result<(), ValidationError>

Validates the key signature using Mojang’s signature validator.

The signature covers: profileId + expiresAt + key bytes

Errors

Returns ValidationError if signature validation fails or cryptographic operations fail

fn signed_payload(&self, profile_id: Uuid) -> Result<Vec<u8>, ValidationError>

Constructs the byte payload that was signed by Mojang.

Format: profileId (16 bytes) + expiresAt (8 bytes) + key bytes

pub fn to_bytes(&self) -> Result<Vec<u8>, ValidationError>

Serializes the key data for network transmission

Errors

Returns ValidationError if key encoding fails

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

Deserializes key data from bytes

Errors

Returns ValidationError if the byte format is invalid or key decoding fails

Panics

Panics if slice-to-array conversion fails (should not happen due to length checks)
