1. A method comprising:
receiving an input comprising cleartext data;
receiving, via an application program interface (API), a password from a user;
receiving, via the API, from a security service server, a derived key generated using the password;
generating an encryption key using the derived key for at least one of a pre-encryption, a core encryption and a post-encryption;
applying the pre-encryption to the input by performing one or more rounds of data transformations, the pre-encryption transforming the cleartext data into non-cleartext data;
applying the core encryption to the non-cleartext data, the core encryption comprising a standard encryption algorithm that transforms the non-cleartext data into encrypted ciphertext;
applying the post-encryption to the encrypted ciphertext, the post-encryption comprising one or more rounds of additional data transformations; and
generating, at a local client device, an encryption of the input based on an output from the post-encryption.
