Introduction

In this Blog we will see how to convert string into MD5 in SQL Server. First we will try to understand what MD5 is.
The MD5 message-digest algorithm is a widely used cryptographic hash function producing a 128-bit (16-byte) hash value, typically expressed in text format as a 32 digit hexadecimal number. MD5 has been utilized in a wide variety of cryptographic applications, and is also commonly used to verify data integrity.

Go to SQL Server and write the below SQL Query.

  1. Select CONVERT(VARCHAR(32), HashBytes('MD5', 'This text is going to be converted to MD5'), 2) as MD5Hash
Execute the preceding command and check the output.



So the MD5 equivalent of “This text is going to be converted to MD5
” is “4DF5BE7CB28FF963C57D51E6D3CCE042”.

Let’s try out one more examples. Execute the following command.
  1. Select CONVERT(VARCHAR(32), HashBytes('MD5', 'Sample Text'), 2) as MD5Hash


The MD5 equivalent of “Sample Text” is “83936A3F80BA44C78C9911F5445F2994”.
