Regex Editor & Tester

Matches a string of exactly 32 hexadecimal characters (digits 0-9 and letters a-f), with the case-insensitive flag allowing uppercase A-F as well. This is the standard length of an MD5 hash digest, making the pattern ideal for validating MD5 checksums, verifying data integrity, or extracting hashes from logs and text. Anchors ensure the entire string is the hash with no extra characters.
