7 SHA1 Message Digest
| (require file/sha1) | 
See openssl/sha1 for a faster implementation.
Returns a 40-character string that represents the SHA-1 hash (in
hexadecimal notation) of the content from in, consuming all
of the input from in until an end-of-file.
The sha1 function composes bytes->hex-string with sha1-bytes.
Example:  | ||
  | 
| (sha1-bytes in) → bytes? | 
| in : input-port | 
Returns a 20-byte byte string that represents the SHA-1 hash of the
content from in, consuming all of the input from in
until an end-of-file.
Example:  | ||
  | 
| (bytes->hex-string bstr) → string? | 
| bstr : bytes? | 
Converts the given byte string to a string representation, where each
byte in bstr is converted to its two-digit hexadecimal
representation in the resulting string.
