PublicKey

Struct PublicKey 

Source 
pub struct PublicKey(/* private fields */);
Expand description

Represents a secp256k1 public key.

The key is internally represented using an AffinePoint and the compressed encoding of it.

The AsRef implementation will always return the compressed representation. However, the TryFrom byte slice accepts any representation.

Implementations§

Source§

impl PublicKey

Source

pub const SIZE_COMPRESSED: usize = 33usize

Size of the compressed public key in bytes

Source

pub const SIZE_UNCOMPRESSED: usize = 65usize
