Section Text
(1) Subject to the provisions of this section any subscriber may authenticate an
electronic record by affixing his digital signature.
(2) The authentication of the electronic record shall be effected by the use of
asymmetric crypto system and hash function which envelop and transform the initial
electronic record into another electronic record.
Explanation.—For the purposes of this sub-section, "hash function" means an
algorithm mapping or translation of one sequence of bits into another, generally smaller,
set known'as "hash result" such that an electronic record yields the same hash result every
time the algorithm is executed with the same electronic record as its input making it
computationally infeasible—
(a) to derive or reconstruct the original electronic record from the hash result
produced by the algorithm;
(b) that two electronic records can produce the same hash result using the
algorithm.
(3) Any person by the use of a public key of the subscriber can verify the electronic
record.
(4) The private key and the public key are unique to the subscriber and constitute a
functioning key pair
