Type: string
EOSKey..
Type: string
Initialize by running some self-checking code. This should take a second to gather additional CPU entropy used during private key generation.
Initialization happens once even if called multiple times.
Returns Promise
Does not pause to gather CPU entropy.
Returns Promise<PrivateKey> test key
cpuEntropyBitsnumber gather additional entropy from a CPU mining algorithm. This will already happen once by default. (optional, default0)
ecc.randomKey().then(privateKey => {
console.log('Private Key:\t', privateKey) // wif
console.log('Public Key:\t', ecc.privateToPublic(privateKey)) // EOSkey...
})seedstring any length string. This is private. The same seed produces the same private key every time. At least 128 random bits should be used to produce a good private key.
ecc.seedPrivate('secret') === wifReturns wif
ecc.privateToPublic(wif) === pubkeyReturns pubkey
ecc.isValidPublic(pubkey) === trueReturns boolean valid

Create a signature using data or a hash.

Verify signed data.

Recover the public key used to create the signature.
