NAME

GPLVote::SignDoc::Client - module for helping create GPLVote SignDoc client software.

SYNOPSIS

 use GPLVote::SignDoc::Client;

 if (user_sign_is_valid($public_key, $sign, $data)) {
    print "Sign of document is CORRECT\n";
 } else {
    print "BAD SIGN!!!\n";
 };

 my $pub_key_id = calc_pub_key_id($public_key);

 my $enc_data = encrypt($public_key, $data);
 

Methods

user_sign_is_valid(base64_plain public_key, base64_plain sign, raw data, boolean sha256sign)

Check signature of data.

public_key - RSA public key for check signature. Encoded in Base64 in one string without special begin/finish strings and without line breaks.

sign - RSA signature. Some format like public_key.

data - signing data for verify signature.

sha256sign - boolean flag for check signature as "SHA256withRSA", else checking as "SHA1withRSA".

Returning true if signature is valid.

split_base64(base_64 string)

Helping method for separate one long line Base64 on different lines with length 72 chars.

calc_pub_key_id(base64_plain public_key)

Calculate ID of public key.

encrypt(base64_plain public_key, raw data)

Encrypt data over public key.

Returning plain Base64 string with encrypted data.
