Abstract
Disclosed herein are system, method, and computer program product embodiments for signing a document by generating a hash value using a smart card. The smart card can receive from a computing device a first hash value generated for the document based on a first hash function, determine a private key based on a private key information stored on the smart card, sign the first hash value by generating a second hash value based on the first hash value using a second hash function and the private key. The second hash value is to authenticate that the second hash value is generated by the smart card based on the first hash value and the private key. The smart card can further assemble a signature package including the second hash value, and transmit the signature package to the computing device.
