Difference Between MD5 and SHA-1 in Tabular Form
- MD5 and SHA-1 hashing algorithms provide one-way encryption which is ideal for storing passwords as you will not normally need to see the unencrypted version. You just hash the password provided by the user and authenticate it by comparing it with what’s stored in the database.
- MD5 uses a hash length of 16 bytes and SHA1 uses 20 bytes. This means that SHA1 is slower but more secure.

- A message-digest algorithm is also called a hash function or a cryptographic hash function.
- It accepts a message as input and generates a fixed-length output, which is generally less than the length of the input message. The output is called a hash value, a fingerprint, or a message digest.
- Message Digest 5 (MD5) processes the input text in 512-bit blocks. These blocks are further divided into 16 32-bit sub-blocks.
- MD5 is a 128-bit hash.
- The MD5 algorithm is intended for digital signature applications, where a large file must be “compressed” in a secure manner before being en private key under a public-key cryptosystem such as RSA.
