​PBKDF2 Encryption is a specific type of Password-Based Key Derivation Function Encryption (PBKDF Encryption) that uses a pseudorandom function, such as hash-based message authentication code (HMAC), to generate a derived key from a password or a passphrase

SHA encryption is a term that refers to a family of cryptographic hash functions that are used to verify the integrity and authenticity of data. A hash function is a mathematical function that takes an input and produces a fixed-length output, called a hash or a digest, that is unique for each input. SHA encryption can be used to generate digital signatures, checksums, passwords and other security applications.

Morse code is a system of communication that uses two different signal durations, called dots and dashes, to encode text characters. It was invented by Samuel F.B. Morse in the 1830s and became widely used for telegraphy, the transmission of messages over long distances by electric wires.
