Field Documentation

n

sigverify_rsa_buffer_t sigverify_rsa_key::n

Modulus, a kSigVerifyRsaNumWords base 2^32 digit integer, little-endian.

Definition at line 48 of file rsa_key.h.

n0_inv

uint32_t sigverify_rsa_key::n0_inv[8]

Negative of the multiplicative inverse of n modulo 2^256, little-endian.

Calculations performed on OTBN (word size: 256 bits) use the whole array while calculations performed on Ibex (word size: 32 bits) use only the first word, which is equal to -n^-1 mod 2^32.
