NAME

       EVP_MD-SHA2 - The SHA2 EVP_MD implementation

DESCRIPTION

       Support for computing SHA2 digests through the EVP_MD API.

   Identities
       This implementation includes the following varieties:

       •   Available with the FIPS provider as well as the default provider:

           SHA2-224
               Known names are "SHA2-224", "SHA-224" and "SHA224".

           SHA2-256
               Known names are "SHA2-256", "SHA-256" and "SHA256".

           SHA2-384
               Known names are "SHA2-384", "SHA-384" and "SHA384".

           SHA2-512
               Known names are "SHA2-512", "SHA-512" and "SHA512".

       •   Available with the default provider:

           SHA2-256/192
               Known names are "SHA2-256/192", "SHA-256/192" and "SHA256-192".

           SHA2-512/224
               Known names are "SHA2-512/224", "SHA-512/224" and "SHA512-224".

           SHA2-512/256
               Known names are "SHA2-512/256", "SHA-512/256" and "SHA512-256".
