Istream& operator>> ( Istream ,
SHA1Digest  
)
friend

Read (40-byte) text representation.

Since leading and intermediate underscores are skipped, a '_' can be prefixed to the text representation to use an unquoted SHA1Digest without parsing ambiguities as a number.

Ostream& operator<< ( Ostream ,
const SHA1Digest  
)
friend

Write (40-byte) text representation, unquoted and without prefix.
