Abstract: Encryption method, corresponding encryption method, devices and programs. The invention relates to a method of encrypting a code to be encrypted (
Sx ) of a computer program using an encryption key (
Kx ) selected from at least two encryption keys (
Kx, Ky, Kz ). Such a method comprises: - a step of obtaining (11) a descriptive grammar (
G D ) of the language of the code to be encrypted; - a step of coding (13) the code to be encrypted (
Sx ) using the descriptive grammar (G
D ) delivering a character string (
Cd
C ) in which at least one start instruction (InstrD) of the code to be encrypted (Sx) is coded by a representation (
RInstrD ) in the character string (
Cd C ); - a step of encoding (14) the character string (
CdC ) using an encryption key (
Kx ) belonging to the set of encryption keys (
Kx, Ky, Kz ), delivering an encrypted string (
Cx ). The decryption method comprises the reverse steps and also makes use of the descriptive grammar of the code to be encrypted.
