Cloud Encryption Algorithm is a component of data transport security. This Algorithm is nothing but some sequence of mathematics. This algorithm varying block ciphers to encrypt electronic 0 and 1.

Encryption algorithms stop data fraud, such as that perpetrated by bad persons who unlawfully obtain electronic information. This Encryption Algorithm is found in software applications and a part of any company’s risk management protocols.

Encryption algorithms help in transforming plain text into encrypted text and again reverse to plain text for the tenacity of securing cloud data when it is transported over networks. You can use Cloud OS for this.

**Cloud Encryption Algorithm**

Encryption algorithms are frequently used in cloud communications, with FTP transfers. Generally, algorithms are used to deliver secure transfers. When a cloud encryption algorithm is used in data transfer, the file at first translated into apparently worthless encryption text and then transferred in this formation; the receiving computer uses a key to interpret the cipher into its unique form. So if the message or file is captured before it reaches the receiving computer it is in an ineffectual (or encrypted) form.

When cloud data is encrypted through **Cloud Encryption Algorithm** data becomes more secure, accurate and safe from bad persons for any fraudulent activities. If the bad persons become more mathematical then the issue is more sophisticated.

Encryption algorithms may vary in size, but the power of an algorithm is usually directly proportional to its size. First Encryption Algorithm was developed by U.S. mathematicians Ron Rivest, Adi Shamir, and Len Adleman in the year 1977.

**How Cloud Encryption Algorithm Works**

Cloud Encryption Algorithm is an exciting piece of technology that works by scrambling information so it is incomprehensible by bad persons. We can show it as an example:

Suppose I want to transfer an encrypted message like “Darling, we will meet 30 February afternoon in your empty house”. The message will be converted like:

wUwLOnkBAf4vxSpQgQZltcz7LWwEquhdm5kSQIkQlZtfxtSTsmaw q6gVH8SimlChL2FdgvdIC7sDv7G1Z7pCNzFLp0lgB9ACm8r5RZOBi N5ske9cBVjlVfgmQ9VpFzSwzLLODhCUrW3NGQZfz3SSWviwCe7G=PAb3

When my text is encrypted normally it becomes a jumbled character and equipped with the secret passcode and will be decoded in a reverse way.

SHA-1 means Secure Hash Algorithm 1. SHA-1 is a cryptographic hash function that receipts an input and yields a 160-bit (20-byte) hash value known as a message digest – naturally extracted as a hexadecimal number, 40 digits size. This **Cloud Encryption Algorithm** is developed by the US National Security Agency and is a U.S. Federal Information Processing Standard.

**Drawbacks/Disadvantages**

**Cloud Encryption Algorithm**is a very multifaceted technology.- Running of encryption keys must be an added administrative job for often overloaded IT staff.
- Another disadvantage of encryption as it narrates to keys is that the security of data becomes the security of the encryption key.
- Lose that key, and you effectively lose your data.
- traditional full-disk encryption solutions are the reduction of overall system performance upon deployment.
