Enter a word in the MD5 encryption form above to know the corresponding MD5 hash. To use a hash for your purposes (see comments on this answer), proceed as follows: Compute HASH = hash(FROM_DATE + TO_DATE + SECRET). But client don't want from and to date to be exposed (though it's ridiculous as validity should always be visible to user!). With a good block cipher (like AES), you can choose between encrypting text as a block (the output will be a 32 character block) and you'll have 256 bit encryption or XORing the text with an encrypted nonce (the output will be a 12 byte ciphertext) and you'll have 96 bit encryption. When you pass keys of different lengths into MCrypt, it will select the appropriate key size automatically, so you don't and can't set it. If each of the individual characters was interpreted as an 8-bit quantity, this gives the 128-bit key size that one would expect. I'll edit my answer to show you how.

Generates 32 random characters (256bits): openssl rand 32 Be aware that strings parsed by NServiceBus do not use extended ASCII which limits the key range to 7 bits per character. Verify that HASH = hash(FROM_DATE + TO_DATE + SECRET). To create a 25 character key you can use Guid.NewGuid Method which returns including hyphens 36 characters or without hyphens 32 characters as there are 4 hyphens returned in each conversion to string of a Guid.NewGuid.
