Updates the Sign content with the given data, the encoding of which is given in inputEncoding. If encoding is not provided, and the data is a string, an encoding of 'utf8' is enforced. If data is a Buffer, TypedArray, or DataView, then inputEncoding is ignored.
For RSA-PSS keys, if the key material contains a RSASSA-PSS-params sequence, the hashAlgorithm, mgf1HashAlgorithm, and saltLength properties will be set.
This is a basic economic principle. If a cryptocurrency has a high token supply with little demand from traders and users, then the cryptocurrency’s value will drop. Conversely, if the supply of a particular cryptocurrency is limited and the demand is high, then the value of the coin will increase.
Use of crypto.timingSafeEqual does not guarantee that the surrounding code is timing-safe. Care should be taken to ensure that the surrounding code does not introduce timing vulnerabilities. algorithm
The outputEncoding specifies the output format of the enciphered data. If the outputEncoding is specified, a string using the specified encoding is returned. If no outputEncoding is provided, a Buffer is returned.

Although Portnoy’s stint seems like a bit of a joke, so did Dogecoin and the proliferation of dog-themed altcoins that piggybacked onto the trend—there’s no saying what can come next.
Notes: This figure plots weekly averages of log price and log computing power (log hashrate) of Bitcoin and Ethereum over the period from August 2015 to January 2019. We normalise both time series by subtracting their mean and dividing by the standard deviation.

The iterations argument must be a number set as high as possible. The higher the number of iterations, the more secure the derived key will be, but will take a longer amount of time to complete.
