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
• elliptic curve: 163 bytes or less
non-export
• non elliptic curve operations: 4096 bytes
• elliptic curve operations: 571 bytes
Limitations to non-export cipher suite types are due to the computational constraints of a BlackBerry® device.
