Program a PHP Encoder / Decoder for specific method

Requirements - need an encryption with the following encryption details Encryption details - The cipher mode used for all encryption types is CBC. - The padding mode used for all encryptions is PKCS7. - Only a user-friendly password will be required for configuration by the user. This password will be used to generate both the key and initialization vector required by the encryption process. - If the password is longer than necessary, it will be truncated to fit. - If the password is shorter than necessary, it will be right padded with asterisks (*). The valid lengths that will determine truncation or padding are defined as being the maximum length allowed for each respective algorithm. Currently, those lengths are defined as follows: Valid key lengths: - DES - 8 bytes - RC2 - 16 bytes - Rijndael - 32 bytes - TripleDES - 24 bytes Valid IV lengths: - DES, RC2, TripleDES - 8 bytes - Rijndael - 16 bytes $key = "Funeral8!***************"; $iv = "Funeral8"; If you decrypt : EEue773qdMY= Do you get : Hello If you decrypt: E/UcoRpG4iAablxXnCLvQWPXP/rEp/XAiWqcrfXsFTm6v3vVa+JnNw== You get: 123456789 Online tester - [login to view URL] Let me know if you can be done in the next hours.
