Overview of Using Cryptography Extensions

A selection of Security and Cryptography classes are supported by the simulator. The support for security and cryptography enables you to:

  • Generate message digests using MD5, RIPEMD160, SHA1 and SHA2 algorithms

  • Generate cryptographic keys on Java Card technology-compliant smart cards for use in the ECC, DSA and RSA algorithms

  • Set cryptographic keys on Java Card technology-compliant smart cards for use in the AES, DES, 3DES, HMAC, ECC, DSA, and RSA algorithms

  • Encrypt and decrypt data with the keys using the AES, DES, 3DES, and RSA algorithms

  • Encrypt and decrypt data and associated data with AES keys using AEAD algorithms

  • Generate and verify signatures using MAC, CMAC, HMAC,DSA, ECDSA, and RSA algorithms.

  • Generate and verify signatures with message recovery using RSA algorithm

  • Generate sequences of random bytes

  • Perform key-agreement with ECC algorithm

  • Generate checksums with CRC algorithms

  • Support padding schemes for signatures and cipher operations

  • Generate derived data using KDF in Counter mode and HKDF for TLSv1.2, TLSv1.3 and DTLSv1.3 algorithms

    Note:

    DES is also known as single-key DES. 3DES is also known as triple-DES.
