EmLib is designed for portability to any device. The modules can be used in PC applications, as well as on embedded target devices.
emLib is optimized for speed performance and a small memory footprint. The sources are completely written in ANSI-C. Validation code for the APIs using standard test patterns is included.
Cryptographic Modules
AES MODULE
Implementation of the AES 128 bit and 256 bit algorithm including chained block processing for en-/decryption of more than 16 Byte of data.
DES MODULE
Implementation of the DES (56 bit) algorithm, also including CBC for processing more than 8 Byte of data. The DES functions can be called multiple times to achieve a higher security (TDES, triple-DES).
Data Integrity Check
CRC LIBRARY
Handling of arbitrary polynomials up to 32 bits wide, in normal and bit-reversed form. In addition to the generic CRC functions, emLib CRC features optimized implementations for popular CRC polynomials including CRC-CCITT, CRC-16, and CRC-32.
ECC LIBRARY
Provides routines for the detection and correction of multiple bit errors. It includes implementations for 4-, 8-, 24- and 40-bit error correction.
