node-pkcs7

A super tiny library to apply and strip PKCS#7 padding.

Example using Crypto and node-pkcs7 to encrypt content with PKCS#7:

function encrypt(content, algorithm, password, IV) {
 
    content = PKCS7.apply(content);
 
    const encrypt = Crypto.createCipheriv(algorithm, password, IV).setAutoPadding(false);
 
    let encryptedContent;
 
    encryptedContent  = encrypt.update(content, 'utf8', 'base64');
    encryptedContent += encrypt.final('base64');
 
    return encryptedContent;
 
}

Example using Crypto and node-pkcs7 to decrypt content with PKCS#7:

function decrypt(encryptedContent, algorithm, password, IV) {
 
    const decrypt = Crypto.createDecipheriv(algorithm, password, IV).setAutoPadding(false);
 
    let content;
 
    content  = decrypt.update(encryptedContent, 'base64', 'utf8');
    content += decrypt.final('utf8');
 
    return PKCS7.strip(content);
 
}
