Aes

Advanced Encryption Standard (AES) is a cryptographic block cipher algorithm.

Rsa

RSA is a common public key algorithm, which can be used for encryption and signature

Slower simpler management

Quality | Example |
---|---|

Much slower |
"Like you heard asymmetric cryptography like rsa is much slower than symmetric cryptography aes but it does have it s advantages simpler key management a single private key to protect" from question "Encrypting/Decrypting large files (.NET)" "Rsa is much slower than aes" from question "Encrypting / Decrypting Lists of data efficiently" "One of the reasons to do so is that rsa is much slower than for example aes" from question "Manual implementation RSA java. Padding ideas" |

Encrypt faster |
"It shows that rsa encrypt is faster then aes encrypt" from question "AES faster than RSA Encryption?" |

Faster |
"The aes key is encrypting much more data but is much faster than rsa encryption" from question "Openssl smime: aes vs rsa - which one encrypts?" |

Execution sizes secs

Quality | Example |
---|---|

More faster |
"Execution of aes is more faster than rsa for same key sizes" from question "RSA Encryption-Decryption of AES key and storing in file" |

Faster |
"So the 115 seconds will be reduced to 3-4 secs plus the encryption decryption time used for aes which is much faster than rsa" from question "RSA encryption results in server execution timeout" |

Secure

Quality | Example |
---|---|

Less secure |
"How is aes less secure than rsa in this scenario" from question "Sending username and password between domains securely" |

More |
"Asymmetric encryption ex rsa is no more secure than symmetric encryption ex aes" from question "Understanding Encryption in Realm" |

More secure |
"Asymmetric key encryption ex rsa is no more secure than symmetric key encryption ex aes" from question "How the RSA algorithm (encryption and decryption) works in real life?" |

Performance resources resource

Quality | Example |
---|---|

Less |
"There are two reasons for that performance aes is faster then rsa and resources aes is less resource hungry than rsa" from question "IOS MDM profile signing, which certificate to use?" |

Faster |
"And regarding your first question it is definitely possible to encrypt decrypt messages directly using rsa there are only technical and performance reasons aes is much faster than rsa why rsa is used only to encrypt a session key and aes is used to encrypt decrypt the messages themselves" from question "Encrypted communication C# <-> PHP using RSA and AES" |
