Convert string or email to MD5 Hash and SHA1 Hash

This tool allows you to generate MD5 and SHA1 hashes from any text string or email address. Both MD5 and SHA1 are cryptographic hash functions that produce fixed-length hash values from input data of any length.

Simply enter your text or email in the input field above and click "Convert" to see both the MD5 and SHA1 hash values. For example:
• "hello" → MD5: "5d41402abc4b2a76b9719d911017c592"
• "hello" → SHA1: "aaf4c61ddcc5e8a2dabede0f3b482cd9aea9434d"

While both hash functions are widely used, it's important to note that MD5 and SHA1 are no longer considered cryptographically secure for sensitive applications. They are still useful for:
• Checking data integrity
• Creating unique identifiers
• Non-security critical applications
• Legacy system compatibility

For modern security applications, stronger alternatives like SHA-256 or SHA-3 are recommended. This tool is primarily for educational purposes and working with systems that specifically require MD5 or SHA1 hashes.

What is an MD5 hash?
An MD5 hash is created by taking a string of an any length and encoding it into a 128-bit fingerprint. Encoding the same string using the MD5 algorithm will always result in the same 128-bit hash output. MD5 hashes are commonly used with smaller strings when storing passwords, credit card numbers or other sensitive data in databases such as the popular MySQL. This tool provides a quick and easy way to encode an MD5 hash from a simple string of up to 256 characters in length. MD5 hashes are also used to ensure the data integrity of files. Because the MD5 hash algorithm always produces the same output for the same given input, users can compare a hash of the source file with a newly created hash of the destination file to check that it is intact and unmodified. An MD5 hash is NOT encryption. It is simply a fingerprint of the given input. However, it is a one-way transaction and as such it is almost impossible to reverse engineer an MD5 hash to retrieve the original string.
