Algorithms and Key Sizes
For the supported algorithms and key sizes, see Algorithms and Key Sizes in the
RSA BSAFE Crypto-C Micro Edition Release Notes included with this release.
Elliptic Curve Support
The following table lists the named elliptic curves this release of MES is designed to
support for cryptographic operations in software and on PKCS #11 hardware devices.
For more information, see
Hardware Devices .
Note: All elliptic curves with a bit strength of 112 or less are disallowed for
use in FIPS compliant applications, and not available for EC operations by
default. For more details, see SP 800-131A, Rev 1, the RSA BSAFE Crypto-C
Micro Edition Security Policy documents included in this release, and
R_LIB_CTX_INFO_ID_MIN_STRENGTH and related identifiers in the
RSA BSAFE Micro Edition Suite Developers Guide.
