Attempting to learn about decryption

1. I am wondering what type of encryption this is, and the steps to go about decrypting it:
   $P$B0GFbv8OYRk.jZxN88dfBO0/iJdLL1

   It’s not encryption, but hashing. The method used by wordpress is called phpass, the implementation can be found in the wordpress code-base for example.

   As it’s not encrypted, you can not decrypt it. You can try to find a plain-text however that matches the hash. This can be done with bruteforcing. A program that does this for the wordpress hashes is hashcat.

2. i think oneway hashing algorithms such as sha1 md5 which outputs a base64 encoded string as the size of the input text to the method

   Example : – PlainText (x) -> sha1() -> base64 String (y)

   always x = y becouse these ciphers are called block ciphers

   These sha1 and md5 functions are considered as one way hash algos

   These functions are considered as

   An algorithm that turns messages or text into a fixed string of
   digits, usually for security or data management purposes. The “one
   way” means that it’s nearly impossible to derive the original text
   from the string.
