What is the maximum length of the string that can have md5 hashed? Or: If it has no limit, and if so what will be the max length of the md5 output value?

The hash size for the MD5 algorithm is 128 bits. The ComputeHash methods of the MD5 class return the hash as an array of 16 bytes. Note that some MD5 implementations produce a 32-character, hexadecimal-formatted hash.
MD5 yields hexadecimal digits (0-15 / 0-F), so they are four bits each. 128 / 4 = 32 characters.
MD5 collision is extremely unlikely. If you have 9 trillion MD5s, there is only one chance in 9 trillion that there will be a collision.
MD5 Message Digest Algorithm, or MD5, is a cryptographic hashing function. It is a part of the Message Digest Algorithm family which was created to verify the integrity of any message or file that is hashed. MD5 is still used in a few cases; however, MD5 is insecure and should not be used in any application.
MD5 processes an arbitrary-length message into a fixed-length output of 128 bits, typically represented as a sequence of 32 hexadecimal digits.
