Function Documentation

APU_DECLARE

(

void

)

const

Provide a means to SHA1 crypt/encode a plaintext password in a way which makes password file compatible with those commonly use in netscape web and ldap installations.

Parameters:

clear	The plaintext password
len	The length of the plaintext password
out	The encrypted/encoded password

Note:

SHA1 support is useful for migration purposes, but is less secure than Apache's password format, since Apache's (MD5) password format uses a random eight character salt to generate one of many possible hashes for the same password. Netscape uses plain SHA1 without a salt, so the same password will always generate the same hash, making it easier to break since the search space is smaller.

Initialize the SHA digest

Parameters:

context

The SHA context to initialize

Update the SHA digest

Parameters:

context	The SHA1 context to update
input	The buffer to add to the SHA digest
inputLen	The length of the input buffer

Update the SHA digest with binary data

Parameters:

context	The SHA1 context to update
input	The buffer to add to the SHA digest
inputLen	The length of the input buffer

Finish computing the SHA digest

Parameters:

digest	the output buffer in which to store the digest
context	The context to finalize
