Strange they mention supporting 521 here [1], but on the compare page they only list 384? [1] https://www.yubico.com/2016/05/secure-hardware-vs-open-source/ https://www.yubico.com/2016/05/secure-hardware-vs-open-sourc... Edit: looking at the PIV tools manual they provide; I can see no mention of the tool supporting 521, it fails when I try to generate a key. Looking through the .h files, I do see mentions of p521 ;) int BN_nist_mod_192(BIGNUM *r, const BIGNUM *a, const BIGNUM *p, BN_CTX *ctx); int BN_nist_mod_224(BIGNUM *r, const BIGNUM *a, const BIGNUM *p, BN_CTX *ctx); int BN_nist_mod_256(BIGNUM *r, const BIGNUM *a, const BIGNUM *p, BN_CTX *ctx); int BN_nist_mod_384(BIGNUM *r, const BIGNUM *a, const BIGNUM *p, BN_CTX *ctx); int BN_nist_mod_521(BIGNUM *r, const BIGNUM *a, const BIGNUM *p, BN_CTX *ctx);
