можно подумать, что при объявлении указателя, символ * относится к имени(не как часть, а как что-то зависящее от него), а не к типу.
const char *a, b; можно превратить в const char (*a), b, но нельзя превратить в const (char *a), b или в char (const *a), b.
Но в режиме отладки всё, как я уже писал выше, работает.
$ gcc -std=c99 -O2 -g3 -fsanitize=address main.c acp.c md5.c -o main
$ ./main
Base64('Hello') = "SGVsbG8="
MD5('Hello') = "8b1a9953c4611296a827abf8c47804d7"
