摘要： Electronic signature functions, such as electronically signing an electronic record, verification of an electronic signature and issuance of keys, may be performed by a server or other central computer. For electronic signing, the server may access a key on a protected database and encryption programs to electronically sign an electronic record. For signature verification, the server may receive the electronic record and electronic signature, determine a key to decrypt the electronic signature, and then determine whether the electronic signature is valid. For issuance of keys, the server may receive a user request to generate keys, may generate the keys, and store the keys in a database which is accessible by the server, but which may not be accessible by the user.
