The Basics

{{ page.summary | capitalize }}. This 25-word phrase (13 words in the case of MyMonero) has all the information needed to view and spend funds from a Monero @account.

In-depth Information

In the official wallet, the mnemonic seed comprises 25 words with the last word being used as a checksum. Those words correspond to a 256-bit integer, which is the account's private @spend-key. The private @view-key is derived by hashing the private spend key with Keccak-256, producing a second 256-bit integer. The corresponding public keys are then derived from the private keys.
