Less secure than SHA256	More Secure than SHA1

 

Describe SHA1

Secure Hash Algorithm 1 is known as SHA1. It is a
cryptographic hash function that takes an input and produces a message digest,
a 160-bit hash value. It is also represented as a 40-digit hexadecimal number.
It was created by the National Security Agency of the United States. However,
SHA-1 was no longer regarded as secure after 2005. As a result, businesses now
substitute SHA2 or SHA3 for SHA1. In 2017, the majority of web browser makers
support SHA1 SSL certificates.

 

Describe SHA256

The term “SHA2” refers to a pair of related hash
algorithms with various block sizes. It includes SHA 256. Any string or input
data can be hashed using a hash generator tool to create a SHA256 hash.
Additionally, the internal state size is 256 bits, and it produces 256 hash values.
Here is an illustration of a SHA1 and SHA256 hash.

 

SHA1 vs. SHA256 Comparison and Differences

SHA1 is a cryptographic hash function that takes an input
and generates a message digest, a 160-bit hash value. On the other hand, SHA256
is a variant of SHA2 that generates a 256-bit hash value. This clarifies the
primary distinction between SHA1 and SHA256.
