Difference Between Stream Cipher and Block Cipher

Difference Between Stream Cipher and Block Cipher in Tabular Form

Comparison Chart

STREAM CIPHER BLOCK CIPHER
In-stream cipher keys and algorithms are applied to each binary digit in a tiara stream, one bit at a time, rather dun encrypting a block of data. Block cipher is the main method of encrypting text in which keys and algorithms are applied to block data rather than individual bits like stream cipher.
A stream cipher is less time-consuming. Block cipher is more time-consuming.
Because of a bit of encrypting at a time. a stream cipher is faster than a block cipher. As a block of data is encrypting at a time block cipher is slower than stream cipher.
Stream Cipher doesn’t use in chaining modes of operation. Block Cipher used in chaining modes of operation.
Hardware implementation is easy using a stream cipher. The software implementation is easy using a block cipher.
One Time Pad is the best example of stream Cipher Data Encryption Standard (DES) is the best example of a block cipher.
Requires less code. Requires more code.
Application: SSL Application: Database,file encryption.
