In cryptography, SHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function designed by the United States National Security Agency and is a U.S. Federal Information Processing Standard published by the United States NIST. SHA-1 produces a 160-bit (20-byte) hash value known as a message digest. A SHA-1 hash value is typically rendered as a hexadecimal number, 40 digits long.
SHA-1 is no longer considered secure against well-funded opponents. In 2005, cryptanalysts found attacks on SHA-1 suggesting that the algorithm might not be secure enough for ongoing use, and since 2010 many organizations have recommended its replacement by SHA-2 or SHA-3. Microsoft, Google and Mozilla have all announced that their respective browsers will stop accepting SHA-1 SSL certificates by 2017.
Here is what you need to do –
- Download openSSl from Code Extract it. create a folder- OpenSSL in C:/ and copy the extracted code here.
- Detect debug.keystore file path. If u didn’t find, then do a search in C:/ and use the Path in the command in next step.
- Detect your keytool.exe path and go to that dir/ in command prompt and run this command in 1 line-it will ask for password, put android that’s all. u will get a key-hash123$ keytool -exportcert -alias androiddebugkey -keystore "C:\Documents and Settings\Administrator.android\debug.keystore" | "C:\OpenSSL\bin\openssl" sha1 -binary |"C:\OpenSSL\bin\openssl" base64
