How many characters are produced for each hash?
MD5 hashes are 128 bits in length and generally represented by 32 hex digits. SHA-1 hashes are 160 bits in length and generally represented by 40 hex digits.
What characters are in a hash?
MD5 and SHA hashes in raw form are binary, however their common representation is a hex-encoded string, which contains characters [a-fA-F0-9] . So if this is what you meant, then characters G-Z, g-z are “excluded”. Another, less common, representation is Base64 encoding [0-9a-zA-Z+/].
What is the output of a hash called?
A hash function is a versatile one-way cryptographic algorithm that maps an input of any size to a unique output of a fixed length of bits. The resulting output, which is known as a hash digest, hash value, or hash code, is the resulting unique identifier we mentioned earlier.
How long is hash MD5?
128 bits
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.
Is hash in hexadecimal?
It’s encoded in hexadecimal so the resulting string is easier to work with and debug. The actual hash is always in binary, but in most programming languages and libraries, the default output from a hash function is an ascii/utf8 string of hexadecimal encoded binary string.
Is there a hash that outputs 8 chars?
When I decode it, I get random 8 chars regardless of password length. The characters consist of random unicode characters. So, I know it’s not an algo that I know like md5, sha, pbkdf etc. Now, I don’t want to crack it if it’s a home brewed hashing algo, but if it’s generic I want to find out what it is.
How is a hash function converted to a character?
So, when a hash function output is meant for human consumption, it is converted to characters with some encoding. Hexadecimal is one of the simplest encoding of bits into characters. It converts a chunk of four bits into a digit or a character in the ‘a’ to ‘f’ range.
What are the names of all hash functions?

How many bits are in a 16 byte MD5 hash?
It’s just hex encoded. A 16 byte md5 hash can contain non-printable characters, so it’s encoded to a 32 char hex string. As others have responded, hash functions (all of them, including MD5, SHA-256, Whirlpool and the dozens of other functions) output bits. The output of MD5 is 128 bits.
