Functions

Checks whether a file is digitally signed

is_signed()
# You can use the "infos" parameter to retrieve all the signature information of the file.
# By default, the parameter is set to false and the function returns true or false if the file is signed.
args = file_path, infos

Allows you to digitally sign a file

sign_file()
# The "encryption_algorithm" parameter is set by default to the "SHA256" algorithm.
# If you wish, you can change it to another hashing/encryption algorithm.
args = file_path, certificate_path, certificate_pdw, encryption_algorithm

Encrypts a file

encrypt_file()
# The password must be 16, 24, or 32 bytes long. (1 character = 1 byte)
args = file_path, password

Decrypts a file

decrypt_file()
# To decrypt the ".enc" file, you must use the same password as during encryption.
# WARNING: If the password entered to decrypt the file is incorrect, the data in your file will be altered and it will be permanently unreadable.
args = file_path, password
