Support for SHA-512/224 and SHA-512/256

Gnanasekar R
Hi,

I would like to know if OpenSSL has support for SHA-512/224 and SHA-512/256. I see init functions for SHA-256 and SHA-224. But could not find one for the 512/t. Is it not supported?

Thanks,
Gnanasekar

Hi!

Note, this is OpenSSL 1.0.1c.

sha.h: int SHA512_Init(SHA512_CTX *c);
evp.h: const EVP_MD *EVP_sha512(void);

Best regards,
Fredrik

Hi!,

Yes, this is SHA-512. I am interested in the 512/t variants for which the IVs and the final digests length differs. I don't see any parameters to mention that. So wondering if support for 512/224 and 512/256 is available.

Regards,

Yes, I have searched a lot for SHA- 2 .
Looks like there is no support for SHA-2 in openssl-fips 1.2

Thanks
