* WiFiClientSecure: use _timeout setting when connecting
This timeout value can be customized via a call to setTimeout function.
Closes https://github.com/esp8266/Arduino/issues/3944.
* WiFiClientSecure: increase default connection timeout to 15 sec
* WiFiClientSecure: don't decrypt when testing for 'connected'
* WiFiClientSecure: don't trash unread decrypted data when writing
When application requests to write data, check if there is any unread
decrypted data left. If there is, don't write immediately, but save the
data to be written. When all decrypted data has been consumed by the
application, send out the saved outgoing data.
Fixes https://github.com/esp8266/Arduino/issues/2256.
* Added constant time strings comparison to avoid possible time-based attacks
* Fixed data types
* Fixed indentation
* Moved string comnparison in constant time to String class; modified function body to assure constant time comparison despite compiler optimizations
* Removed wrong code
* Fixed error and prevented compiler optimization to delete u1 local variable
* Avoid timing attacks on string comparison
* Minor
* changed counter names, removed else
* EEPROM Library:
Improved put function, compare data and only in case are different set _dirty flag, copy the data
* It will grant that the _dirty flag is reset only at EEPROM.commit() and no changes are lost
Mainly useful for testing WiFiClientSecure in local environments.
If allowSelfSignedCerts is called before verifyCertChain, then the
certificate chain will be verified, but the final certificate may be
self-signed.
* ifndef'd LWIP_OPEN_SRC to prevent a redefined warning
* ABORT on NOTIFY to prevent responding to NOTIFY messages (we should only respond to M-SEARCH messages)
* case-insensitive compare of _deviceType to enable response to all-lowercase Alexa queries (robustness principle)
* Add Digest Auth
* Check for Opaque and Nonce
* Remove Serial Debug and fix Indentation
* Added example sketch with documentation,Fixed indentation and Defaults
* Digest Authentication minor changes + new padded 32 digit random function
* update license to public domain
* renaming functions
