interface
Crypto¶ Message encryption functions.
Supports key generation, encryption, decryption, and hashing.
Performs ECIES encryption with the bitcore-ecies 1.0.3 default configuration.
-
Crypto.decrypt(cryptogram)¶ Decrypt cryptogram for active key pair.
Generate or restore key pair prior to use.
Arguments: - cryptogram (Base64) – Cryptogram to decrypt.
Throws: MissingValueError – If key pair has not been generated or restored.
Returns: string – The decrypted message.
-
Crypto.encrypt(message, recipient, network="<mainnet>")¶ Encrypt message for public key.
Arguments: - message (string) – Message to encrypt.
- recipient (HexString) – Public key of recipient.
- network – Bitcoin Cash network.
Returns: Base64 – The cryptogram.
-
Crypto.exportPrivateKey()¶ Export private key as hex string.
Generate or restore key pair prior to use.
Throws: MissingValueError – If key pair has not been generated or restored. Returns: HexString – Private key.
-
Crypto.exportPublicKey()¶ Export public key as hex string.
Generate or restore key pair prior to use.
Throws: MissingValueError – If key pair has not been generated or restored. Returns: HexString – Public key.
-
Crypto.generateKeyPair(network="<mainnet>")¶ Generate ECDSA key pair for message encryption.
Generated key pair is saved internally and used for subsequent operations. No return value. Subsequent calls discard and replace old key pair.
Arguments: - network – Network to generate for. Type implementation defined.
-
Crypto.hash(text)¶ Hash a string with SHA-224.
Arguments: - text (string) – Text to hash.
Returns: ArrayBuffer – SHA-224 hash of the text.
