Aug 03, 2015 · The SSH protocol specification requires implementations to support at the least the following two DH key exchange methods: diffie-hellman-group1-sha1. diffie-hellman-group14-sha1. Both methods use an Oakley group; the first method uses the Oakley Group 2 of size 1024 bits and the second method uses the Oakley Group 14 of size 2048 bits.

Apr 19, 2018 · Attackers can use known weakness in SHA-1 to do man-in-middle attacks, compromise data integrity, or perform spoofing. Microsoft, Google and others had announced their SHA-1 deprecation plans since 2011, to gradually shift from SHA-1 to SHA-2, a more secure alternative.

What's the key size of the private key? Actually the code is using SHA1 and not SHA256 for the hash algorithim. the hash has been confirmed to be correct yeah?

MD5 was used for a number of years until it was found to have a security flaw in 2004 which set the stage for SHA-1. Hash algorithms take a variable length input string and reduce it to a typically shorter and fixed length output (160 bits for SHA-1), the goal of which being to provide a unique identifier for that input.

To generate an API key you require, SHA1 fingerprint of your keystore. Keystore is basically a place where the private keys for your app are kept. In simple words its a certificate generated by user or a program, used for signing an Android app. Solved: I want to change my signature algorithm from SHA1 TO SHA256, my ASA IOS version is 8.4 It is CSR successfully checked Signature algorithm:SHA1 Key algorithm:RSA Key size:2048 to be Signature algorithm:SHA256 Key algorithm:RSA Key size:2048
