What is a .JMC file extension?

.JMC file extension is created by JM-Crypt Security. .JMC has been classified as Encoded Files.

.JMC is JM-Crypt Encrypted File

File encrypted by the JM-Crypt encryption algorithm; stores a file protected by a hybrid encryption algorithm and password.

The JMC file is commonly used to encrypt confidential personal files, as well as sensitive business files, when sharing them with other users. JM-Crypt also uses the ".jmcx", ".jmck", ".jmcp", ".jmcr", and ".jmce" file extensions for encrypting files.

The JM-Crypt algorithm uses the one-time pad (OTP) encryption method and twice encrypts the file. The first encryption is with a random extract of a long random key generated by JM-Crypt Security's homemade fast Fourier transform (FFT) key generator. The second encryption includes password protection that depends on the method selected by the user, which may be fully automatic, semi-automatic (project mode), or manual (a password created by the user and featured in the JMC file), and includes password protection.

NOTE: In order to decrypt the JMC file, you need the JM-Crypt software and algorithm that were used to originally encrypt the file.
