Hash algorithms that the RIM Cryptographic API

supports

Direct mode SSL Direct mode TLS WTLS

MD5 MD5 SHA

SHA-1 SHA-1 SHA-40, SHA-80, MD5, MD5-40,

MD5-80

Limitations of RIM Cryptographic API

support for cipher suites for the key

establishment algorithm

The RIM Cryptographic API implementation of the TLS protocol and WTLS protocol supports the use of the RSA public key

algorithm, DSA public key algorithm, and Diffie-Hellman key exchange algorithm, with the following limitations.

Cipher suite type Typical component limitation

export RSA and Diffie-Hellman: 1024 bytes or less

non-export non elliptic curve operations: 4096 bytes

Limitations to non-export cipher suite types are due to the computational constraints of a BlackBerry device.
