crypto: SHA1_Init deprecated at openssl 3.0

From https://www.openssl.org/docs/man3.0/man7/migration_guide.html

> Use of low-level digest functions such as SHA1_Init(3) have been informally
> discouraged from use for a long time. Applications should instead use the
> high level EVP APIs EVP_DigestInit_ex(3), EVP_DigestUpdate(3) and
> EVP_DigestFinal_ex(3), or the quick one-shot EVP_Q_digest(3).
