SHA-1-PBE for 40-bit RC4, denoted CKM_PBE_SHA1_RC4_40, is a mechanism used for generating a 40-bit RC4 secret key from a password and a salt value by using the SHA-1 digest algorithm and an iteration count. The method used to generate the key is described above.
It has a parameter, a CK_PBE_PARAMS structure. The parameter specifies the input information for the key generation process. The parameter also has a field to hold the location of an application-supplied buffer which will receive an IV; for this mechanism, the contents of this field are ignored, since RC4 does not require an IV.
The key produced by this mechanism will typically be used for performing password-based encryption.
