great customer service - sam great, easy to use, saves us a fortune on an extra phone line for a fax. Great customer service, I always use live chat and get answers and resolution within a few minutes. I have only had to use support 3 times in a year because the program is so user friendly.

Good overall experience pdfFiller does have a robust feature set for all document needs and the user interface was pleasant to use and mostly intuitive. I believe that a market for single users is far less likely since a normal user would not require most of the features that pdfFiller has to offer and they would probably not use the paid version. I would give 5-stars but you have to sign up in order to download your PDFS/Docs, i would recommend that you allow at least 2 Docs to be edited and downloaded before requiring sign-up.

Quick to respond and follow through I had an issue and emailed the company and not only did 2 different people respond immediately they resolved my issue within a few hours of me sending the email. I’ve never seen that quick of a response before. Very impressive.

What do you like best? The link to fill option and the ability to manipulate pdfs. What do you dislike? Nothing yet. I plan to purchase again next year. What problems are you solving with the product? What benefits have you realized? Quicker document processing with the link to fill feature allowing to obtain digital signatures.

Public key cryptography allows someone to send their public key in an open, insecure channel. Having a friend's public key allows you to encrypt messages to them. Your private key is used to decrypt messages encrypted to you.
Public-key encryption is a cryptographic system that uses two keys -- a public key known to everyone and a private or secret key known only to the recipient of the message. Example: When John wants to send a secure message to Jane, he uses Jane's public key to encrypt the message.
Public key cryptography involves two keys: a private key that can be used to encrypt, decrypt, and digitally sign files, and a public key that can be used to encrypt and a Verity digital signatures.
Public key cryptography uses a pair of keys to encrypt and decrypt data to protect it against unauthorized access or use. The RSA algorithm is popular because it allows both public and private keys to encrypt messages so their confidentiality and authenticity remain intact.
Unlike symmetric key algorithms that rely on one key to both encrypt and decrypt, each key performs a unique function. The public key is used to encrypt and the private key is used to decrypt. It is computationally infeasible to compute the private key based on the public key.
Also known as asymmetric-key encryption, public-key encryption uses two different keys at once -- a combination of a private key and a public key. This makes the system extremely secure, because there is essentially an infinite number of prime numbers available, meaning there are nearly infinite possibilities for keys.
Asymmetric Encryption uses two distinct, yet related keys. One key, the Public Key, is used for encryption and the other, the Private Key, is for decryption. As implied in the name, the Private Key is intended to be private so that only the authenticated recipient can decrypt the message.
Asymmetric Encryption is also known as Public Key Cryptography, since users typically create a matching key pair, and make one public while keeping the other secret. In this case, only the intended recipient can decrypt the message, since only that user should have access to the required secret key.
