What cryptographic features does Java Card support?

Julien SIMON

Java Card 2.1.1 offers the following cryptographic features:

  • javacardx.crypto.Cipher provides encryption/decryption, using either secret-key algorithms (DES, Triple DES) or public-key algorithms (RSA).
  • javacard.security.Signature provides signature/verification using either secret-key algorithms (DES, Triple DES) or public-key algorithms (RSA, DSA).
  • javacard.security.MessageDigest provides message digests, using one-way hash functions (MD5, SHA-1, RIPEMD160).

Please refer to the Java Card specification for more information on supported key lengths, modes of operations and padding.

Note that Java Card 2.1.1 supports neither AES (Advanced Encryption Standard) nor Elliptic Curves. However, they probably will be part of Java Card 2.2.
