Module openbook::signature

Functionality for public and private keys.

Modules

• keypairfull
• null_signerfull
• presignerfull
• signersfull

Structs

• Keypair
  A vanilla Ed25519 key pair
• NullSigner
  NullSigner - A Signer implementation that always produces Signature::default(). Used as a placeholder for absentee signers whose ’Pubkey` is required to construct the transaction
• Presigner
  A Signer implementation that represents a Signature that has been constructed externally. Performs a signature verification against the expected message upon sign() requests to affirm its relationship to the message bytes
• Signature

Enums

• ParseSignatureError
• PresignerError
• SignerError

Constants

• SIGNATURE_BYTES
  Number of bytes in a signature

Traits

• EncodableKey
  The EncodableKey trait defines the interface by which cryptographic keys/keypairs are read, written, and derived from sources.
• EncodableKeypair
  The EncodableKeypair trait extends EncodableKey for asymmetric keypairs, i.e. have associated public keys.
• SeedDerivable
  The SeedDerivable trait defines the interface by which cryptographic keys/keypairs are derived from byte seeds, derivation paths, and passphrases.
• Signable
• Signer
  The Signer trait declares operations that all digital signature providers must support. It is the primary interface by which signers are specified in Transaction signing interfaces

Functions

• generate_seed_from_seed_phrase_and_passphrase
• keypair_from_seed
  Constructs a Keypair from caller-provided seed entropy
• keypair_from_seed_and_derivation_path
  Generates a Keypair using Bip32 Hierarchical Derivation if derivation-path is provided; otherwise generates the base Bip44 Solana keypair from the seed
• keypair_from_seed_phrase_and_passphrase
• read_keypair
  Reads a JSON-encoded Keypair from a Reader implementor
• read_keypair_file
  Reads a Keypair from a file
• unique_signers
  Removes duplicate signers while preserving order. O(n²)
• write_keypair
  Writes a Keypair to a Write implementor with JSON-encoding
• write_keypair_file
  Writes a Keypair to a file with JSON-encoding
