Description
This encrypts the input data with AES-CCM using keytype2, when the input noncesize is <12 the low 2-bits are cleared in the noncesize. The 12-byte nonce buffer used by NS is cleared to all-zero, then the nonce from inputbuf+blocksize with the noncesize is copied to this nonce buffer. NS then copies the data at inputbuf+0 to outbuf+noncesize, with the blocksize.
NS then copies the data at inbuf+blocksize+noncesize to outbuf+blocksize, with size inputbuffersize-blocksize-noncesize. NS then uses PS:EncryptSignDecryptVerifyAesCcm with keytype2 and with the above nonce buffer, where the input/output buffer ptrs are outbuf+noncesize, with size blocksize+(inputbuffersize-blocksize-noncesize). NS then copies the the nonce from the nonce-buffer with the noncesize, to outbuf+0.
