Enter the password protecting your private PGP key. This password must be identical to the password you used when generating your PGP key. If you cannot remember your password, then you cannot decrypt messages.

Since August 1st, iGolder is no longer accepting new accounts and balances can only be redeemed. During the past years, we have been recommending Bitcoin more than our own payment system. We believe in physical gold ownership, and developed iGolder as a mechanism for people to acquire physical gold by trading with one another.

Since iGolder has a central point of failure our server may be raided by thugs wearing some kind of uniformwe feet it is safer for us to cease operations.

The iGolder experiment has been personally rewarding as we met many gold enthusiasts and also learned about Bitcoin in the process. For those who have no idea what Bitcoin is, we recommend doing your own research.

Bitcoin is far superior to iGolder in every way, both in privacy and security as our server is always vulnerable to confiscation.

Bitcoin is a communication protocol with a built-in "escrow service" capable of protecting both the buyer and the seller, rendering our Safetransit completely redundant. For those having gold in their iGolder account, we will ship the physical metal to anyone having more than 1 ounce of gold, assuming the owner is willing to assume the shipping costs. For smaller quantities, we offer to settle in Bitcoin, however we will also settle with any other reasonable payment system.

We will give everyone at least two full years until to contact us to claim their gold. After that period, any unclaimed gold will go to fund an economic development project in Honduras helping local people to become entrepreneurs.

We sincerely wish you the best in life and hope to keep in contact with you. Yours in liberty, The iGolder Team. Update Since we announced we no longer accept gold transfers, we have received countless emails asking to keep the free gold charts and the PGP encryption tools.

We plan to keep running the domain iGolder. Better, we are developing state of the art open-source software for a secure decentralized social network with a built-in wallet.Before, we understand Encryption vs.

Decryption let's first understand- What is Cryptography? Cryptography is used to secure and protect data during communication. It is helpful to prevent unauthorized person or group of users from accessing any confidential data. Encryption and decryption are the two essential functionalities of cryptography. A message sent over the network is transformed into an unrecognizable encrypted message known as data encryption.

At the receiving end, the received message is converted to its original form known as decryption. In this tutorial, you will learn What is Cryptography?

What is meant By Encryption? What is meant by Decryption? Why use Encryption and Decryption? Encryption is a process which transforms the original information into an unrecognizable form.

This new form of the message is entirely different from the original message. That's why a hacker is not able to read the data as senders use an encryption algorithm. Encryption is usually done using key algorithms. Data is encrypted to make it safe from stealing. However, many known companies also encrypt data to keep their trade secret from their competitors.

Encryption Process What is meant by Decryption? This method is performed by un-encrypting the text manually or by using keys used to encrypt the original data. Encryption is done by the person who is sending the data to the destination, but the decryption is done at the person who is receiving the data.

The same algorithm with the same key is used for both the encryption-decryption processes. Here, are important reasons for using encryption: Helps you to protect your confidential data such as passwords and login id Provides confidentiality of private information Helps you to ensure that that the document or file has not been altered Encryption process also prevents plagiarism and protects IP Helpful for network communication like the internet and where a hacker can easily access unencrypted data.

It is an essential method as it helps you to securely protect data that you don't want anyone else to have access. Types of Keys Symmetric Key: Symmetric-key encryption are algorithms which use the same cryptographic keys for both encryption of plaintext and decryption of ciphertext.

Asymmetric Key: Asymmetric encryption uses 2 pairs of key for encryption. Public key is available to anyone while the secret key is only made available to the receiver of the message. This boots security. Public Key: Public key cryptography is an encryption system which is based on two pairs of keys. Public keys are used to encrypt messages for a receiver. It can be used in asymmetric encryption as you can use the same key to encrypt and decrypt data.

Pre-Shared Key: In cryptography, a pre-shared key PSK is a shared secret which was earlier shared between the two parties using a secure channel before it is used.This simple tool allows you to encode and decode messages with a simple substitution cipher.

For a cipher breaker, see Substitution cipher breaker. You can read a cipher description and some considerations regarding the strength of a cipher below the calculator. According to Wikipediain cryptography, a substitution cipher is a method of encrypting by which units of plaintext are replaced with ciphertext, according to a fixed system; the "units" may be single letters the most commonpairs of letters, triplets of letters, mixtures of the above, and so forth. The receiver deciphers the text by performing the inverse substitution.

A simple substitution is the substitution of single letters separately. The substitution key is usually represented by writing out the alphabet in some order.

The Caesar cipher is a form of a simple substitution cipher. This means that A is replaced with C, B with D, and so on. The number of all possible keys for a simple substitution cipher is a factorial of 26 26! However, you can break it if you have enough ciphered text by using frequency analysis or the stochastic optimization algorithm check out our Substitution cipher breaker. Paste text into the field, fill the key, choose "encode" if you have pasted clear text or "decode" if you have pasted ciphered text, and press "Calculate".

If Hexadecimal is checked, the key is given as a sequence of hexadecimal digits: 0 — 9a — f or A — Fwhich should be 32 bytes 64 hexadecimal digits in length for maximum security. The Generate button may be used to create a key in either text or hexadecimal format depending on which button is checked sufficiently long to provide maximum security using a high quality pseudorandom number generator seeded from the time the page was loaded, the time you pressed the Generate button, and the time of keystrokes and various other events since the page was loaded.

You can generate lists of keys suitable for exchanging with correspondents using our companion Pass Phrase Generator page. Enter or paste the text to be encrypted into the following box. If you wish to encrypt a binary file for example, an image or an audio fileuse a utility like Base64 to encode it as text before encryption. Press the Encrypt button to encrypt the text with the above key; the encrypted text will be placed in the Cipher Text box, encoded as text with the Encoding you've selected.

If you prefer to camouflage your message as nonsense English text, first encrypt it in any of the encodings, then select, copy, and paste the text into our Steganography hidden writing page. To decrypt an enciphered message, paste it in the box below, enter the key with which it was encrypted in the Key box at the top, and press the Decrypt button. The decrypted text will be placed in the Plain Text box above. Text before and after the encrypted message is ignored, and the encoding used by the message is determined automatically.

You can decrypt only one message at a time; if more than one encrypted message is pasted into the box below, only the first will be decrypted.
