WebFeb 3, 2009 · Often a hash digest is stored as the ASCII representation of hex digits, for example MD5 of the word 'hash' is: 0800fc577294c34e0b28ad2839435945 This is a 32-character ASCII string. But MD5 really produces a 128-bit binary hash value. This should require only 16 bytes to be stored as binary values instead of hex digits.

MD5 generates an output (128 bit) which is represented using a sequence of 32 hexadecimal digits, which in turn are 32*4=128 bits. 128 bits make 16 bytes (since 1 byte is 8 bits). WebJan 25, 2024 · Effectively, the set of SHA-256 hash values stored in the PDB file of the binary executable file collectively becomes the identifiers in the “birth certificate” of the binary executable file, as these identifiers are registered by the compiler that “gives birth” to the binary executable file.
