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
