Public Key Why Does The Length Of A Bitcoin Key Vary

Bytes Show details

The length of a key doesn't vary. Private keys are always 32 bytes, and public keys are always 65 bytes (or 33 bytes for a compressed public key). Public key hashes are always 20 bytes. The length of addresses vary because in Bitcoin's base58 encoding, leading zero bytes are expressed as a single "1". Other bytes require more than one character

Public Key How Does Bitcoin Work?

Public Show details

However, in Bitcoin we now more commonly hash160 our public key before giving it away. The public key is then used only when we come to unlocking the output.

For the protocol, the number of possible public addresses is actually a lot smaller than the number of possible private keys. This is due to the fact that a public address is a so-called RIPEMD-160 hash of the public key (N.B. the public key is not the same thing as the public address!), and they are “only” 160 bits (20 bytes) in size.
