====== ESYA Electronic Signature API ======


[[:en:esya:aaa:acik-anahtar-altyapisi|Public Key Infrastructure]]


Public Key Infrastructure provides services like authentication, message integrity and confidentiality by using both asymmetric and symmetric cryptography enabling a practical and secure  way of key distribution, signing ,and encryption.


[[:en:esya:eimza:elektronik-imza|Electronic Signature]]


Electronic Signature Law 5070 defines secure electronic signature which provides authentication, message integrity and non-repudiation.

This document describes main operation adn the usage of  ESYA Certificate Validation API. In order to clarify  the subject, the concepts of certificate and certificate validation is shortly summarized.


[[:en:esya:ortakimza:eimza-ortak-kutuphanesi|Electronic Signature Common API]]


ESYA Electronic Signature Common API supports different types and formats of signatures by providing a common interface. The API users are recommended to use this Common API for all kinds of signature operations (except xml/envelope signature format)

[[:en:esya:asic:eimza-asic-kutuphanesi|ASiC Signature API]]


ESYA ASiC API can create [[http://www.etsi.org/deliver/etsi_ts/102900_102999/102918/01.03.01_60/ts_102918v010301p.pdf|ETSI TS 102 918]] compliant signatures, which enables creation of zip files containing one or multiple signature, signed data(s), and verification data(s) .


[[:en:esya:cmszarf:cms-zarf|CMS Envelope]]


CMS Envelope structure is used to create encrypted data.


[[:en:esya:smartcard:akıllı-kart|Smartcard]]


Smartcards are needed to perform cryptographic operations in a secure environments and they provide a safe  container for the private keys not allowing any unauthorized access.
