std.digest.sha
- Computes SHA1 and SHA2 hashes of arbitrary data. SHA hashes are 20 to 64 byte
- quantities (depending on the SHA algorithm) that are like a checksum or CRC,
- but are more robust. *

- SHA2 comes in several different versions, all supported by this module:
- SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224 and SHA-512/256.
- This module conforms to the APIs defined in
std.digest. To understand the - differences between the template and the OOP API, see
std.digest. - This module publicly imports
std.digestand can be used as a stand-alone - module.

structSHA(uint hashBlockSize, uint digestSize)
Template API SHA1/SHA2 implementation. Supports: SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224 and SHA-512/256.
The hashBlockSize and digestSize are in bits. However, it's likely easier to simply use the convenience aliases: SHA1, SHA224, SHA256, SHA384, SHA512, SHA512_224 and SHA512_256.
See std.digest for differences between template and OOP API.
