Online Encrypt Decrypt String

Encrypt text and files on PC

URL Encode and Decode Tool
The best practice is to use several random words. In the absence of other controls this does not provide protection against replay attacks. What would have been a better technique? Basically it is a flawed premise. The values passed in the query string directly controls what is being displayed to the user. If you could share this tool with your friends, that would be a huge help:

Decode from URL encoded format

Safe and secure All communications with our servers are made through secure SSL encrypted connections https. Uploaded files are deleted from our servers immediately after the decode or encode process, and the resulting downloadable file is deleted right after the first download attempt, or 15 minutes of inactivity. We do not keep or inspect the contents of the entered data or uploaded files in any way.

Using percent-encoding, reserved characters are represented using special character sequences. The sets of reserved and unreserved characters and the circumstances under which certain reserved characters have special meaning have changed slightly with each revision of specifications that govern URIs and URI schemes.

RFC section 2. Percent-encoding reserved characters When a character from the reserved set a "reserved character" has special meaning a "reserved purpose" in a certain context, and a URI scheme says that it is necessary to use that character for some other purpose, then the character must be percent-encoded. Percent-encoding a reserved character involves converting the character to its corresponding byte value in ASCII and then representing that value as a pair of hexadecimal digits.

Reserved characters after percent-encoding! In the "query" component of a URI the part after a? The character does not need to be percent-encoded when it has no reserved purpose. URIs that differ only by whether a reserved character is percent-encoded or appears literally are normally considered not equivalent denoting the same resource unless it can be determined that the reserved characters in question have no reserved purpose.

This determination is dependent upon the rules established for reserved characters by individual URI schemes. Percent-encoding unreserved characters Characters from the unreserved set never need to be percent-encoded. URIs that differ only by whether an unreserved character is percent-encoded or appears literally are equivalent by definition, but URI processors, in practice, may not always recognize this equivalence.

For maximum interoperability, URI producers are discouraged from percent-encoding unreserved characters. URI scheme specifications should, but often don't, provide an explicit mapping between URI characters and all possible data values being represented by those characters.

Binary data Since the publication of RFC in it has been specified[1] that schemes that provide for the representation of binary data in a URI must divide the data into 8-bit bytes and percent-encode each byte in the same manner as above. The use of unencoded characters for alphanumeric and other unreserved characters is typically preferred as it results in shorter URLs. Absolutely no internal information about the Web application is revealed to potential attackers.

Attackers cannot see the request details or the URL parameters because they are encrypted. URL encryption is transparent and requires no changes to the application. There is no learning phase necessary for the URL encryption and Smart Form protection engine to instantly protect a Web application. The configuration is very simple: At least one entry URL must be defined see configuration below.

All further links and documents accessible from that entry page are then automatically protected. The user requests the web application's entry page, e.

The web application returns an HTML document containing many links that lead to further pages of the same web application. Airlock processes the document and encrypts all URLs, i. Beyond the entry page, all further requests must have encrypted URLs. Manipulated or unencrypted URLs will be blocked. There is a separate article that explains how to use URL encryption.
