7. Website Protected By The Obsolete SHA-1 Algorithm

Google also announced that it will end support for less secure SHA-1 websites and that all website administrators will be prompted to switch to secure SHA-2.

The reason for this change in SHA-1 is its hash value. SHA-1 uses a maximum hash value of 160 bits, which increases the likelihood of collision attacks. The hash function of the SHA-2 algorithm is up to 512 bits, which avoids the possibility of collision attacks.
