Why and how we can bypass restricted paid WiFi's at public places such as airports, etc ?

            We might be wondering some times on how to bypass the restricted paid wifi in public places to access particular URL . To bypass some poorly configured WiFi's just append (without the double quotes)   " ?.jpg  " to end of your URL string. This should work in many instances where generally blocker is configured let images through.  Appending ?.jpg to the URL makes the blocker think that the URL is an image. On the other hand, anything after the ? doesn't change the actual webpage requested, it only changes the GET headers. (so http://google.com/?.jpg and http://google.com/ give the same page). Note that if there already is a query string in the URL (something after a question mark), then you must use &.jpg instead of ?.jpg, as only the first question mark is considered for making a query string

How to extract signing certificates from macOS binary files

Code signing is a macOS security technology that you use to certify that an app was created by you. Once an app is signed, the system can detect any change to the app—whether the change is introduced accidentally or by malicious code. As Apple Developer site says ( click here for more details  on code signing) : code signing allows the operating system to: Ensure that a piece of code has not been altered since it was signed.  The system can detect even the smallest change, whether it was intentional (by a malicious attacker, for example) or accidental (as when a file gets corrupted). When a code signature is intact, the system can be sure the code is as the signer intended. Identify code as coming from a specific source (a developer or signer).  The code signature includes cryptographic information that unambiguously points to a particular author. Determine whether code is trustworthy for a specific purpose.  Among other things, a developer can use a ...

How to get a certificate fingerprint as SHA-256, SHA-1 or MD5 using OpenSSL on mac

As per my old post ( http://anandmpandit.blogspot.in/2016/11/how-to-extract-signing-certificates.html ) , we can extract the binary signing certificates on mac using codesign tool. If you needed to get fingerprint details of the certificate in MD5, SHA1 or SHA256 format then you have run below steps on the extracted certificate file on macOS. SHA256: SHA256 Fingerprint=D3:0A:32:6C:77:77:93:B5:45:20:AC:C0:D4:7E:3A:84:34:50:96:54:08:7F:7D:63:4C:3E:06:3B:E8:1F:C1:90 SHA1: SHA1 Fingerprint=BF:2C:93:1F:BD:88:E5:4C:96:D8:86:D5:F1:E6:9B:B7:DE:76:51:62 MD5: MD5 Fingerprint=3C:A3:3B:76:6D:AE:3F:4B:4E:B2:AA:66:97:55:B8:76
