> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Secret key of an asymmetric key pair, or the seed or mnemonic phrase from which a cryptocurrency wallet derives its keys. Whoever knows it can sign on behalf of the owner or spend the wallet's funds. Specific formats are separate datatypes: wifaddrcomp and wifaddruncomp (Bitcoin WIF keys), bip32addr (extended keys), bip39_mnemonic (seed phrases), x509_private_key and pgp_private_key_block. Use this record when only the field name tells that a value is a private key.
