crypto

DecryptKey decrypts a key from a json blob, returning the private key itself.

Encode encodes b as a hex string with 0x prefix.

EncryptKey encrypts a key using the specified scrypt parameters into a json blob that can be decrypted later on.

FromECDSA exports a private key into a binary dump.

LightScryptN is the N parameter of Scrypt encryption algorithm, using 4MB memory and taking approximately 100ms CPU time on a modern processor.

LightScryptP is the P parameter of Scrypt encryption algorithm, using 4MB memory and taking approximately 100ms CPU time on a modern processor.

StandardScryptN is the N parameter of Scrypt encryption algorithm, using 256MB memory and taking approximately 1s CPU time on a modern processor.

Version 4 "random" for unique id not derived from key data to simplify lookups we also store the address we only store privkey as pubkey/address can be derived from it privkey in this struct is always in plaintext.
