Information encryption method and mobile terminal

The invention provides an information encryption method and a mobile terminal and relates to the field of mobile communication. The security problem of leaking information of a user through a terminal is solved. The method includes the steps that an encryption instruction is obtained; according to the encryption instruction, plaintext inside an input box is encrypted to obtain ciphertext; the ciphertext is used for replacing the plaintext to be displayed. According to the technical scheme, the information encryption method and the mobile terminal are suitable for communication software, and input information in the communication software is encrypted.
