Abstract
Information system security is important to protect system user data. One form of information system security implementation is to encrypt data using hashing techniques. The bcrypt algorithm and the MD5 algorithm are hashing techniques that are often used to encrypt data. Both of these algorithms aim to hash data, although they have the same purpose, the characteristics of these two algorithms are different. This study aims to analyze the comparison of hashing techniques using the MD5 algorithm with the bcrypt algorithm in encrypting data. This study uses a qualitative approach with literature study research methods and experiments by conducting direct testing of the bcrypt and MD5 algorithms in the data encryption process using the PHP programming language. The results show that the bcrypt algorithm will produce different hashing values even though the hashed data is the same data with a constant hashing value length of 60 characters and consists of a random combination of symbols, letters and numbers. Meanwhile, the MD5 algorithm will produce the same hashing value with the same hash data with a constant hashing value length of 32 characters and consists of a random combination of letters and numbers.
