Encryption Methods

Password Encryption

• Algorithm: SHA-256
• Content : Password
• Salt: User's username

Operation Encryption

• Algorithm: SHA-256
• Content : Func
• Output: Hexadecimal representation of the hash value

Token Generation

• Generates a random UUID and returns its hexadecimal representation.

Six-Digit Token (token_s6)

• Generates a six-digit random number.
