Abstract:
Disclosed are a digital signature generation method and apparatus, and a computer device. The method comprises the following steps: selecting, from values of at least two key value pairs, a specified digit of characters to form an initial character string; conducting encryption processing on the initial character string to generate an encrypted character string; and generating a digital signature according to the encrypted character string.
