    at last she made wrong
    you can correct it through this comment
    A. EI gamal key generation:
    Select a large prime number ‘p’
    Select encryption key ‘e′1
    to be primitive root of mod p
    Select decryption key ‘d’ such that 1≤d≤p−2
    Select encryption key ‘e′2
    such that
    e2=ed1 mod p
    Form the set i,e public key (e1,e2,p)
    to be announced publicly
    Private Key 'd' to be kept secret.
    B. EI gamal key encryption:
    Select a random number ‘r’
    Compute the first part of ciphertext ‘c′1,c1=er1modp
    Compute the second part of ciphertext ‘c′2,c2=(er2∗PT)modp
    C. EI gamal key decryption:
    Calculate the PT
    PT=(c2∗(cp−1−d1))modp
    Example 1:
    let Plaintext M = 7
    e1
    = 2
    d = 3
    Random no 'r' = 4
    1. Key generation:
    p=11e1=2d=3
    e2=ed1 mod p=23mod11=8 mod 11=8
    2. Encryption:
    c1c2Random no r=4=er1 mod p=24 mod 11=16 mod 11=5=Pt∗er2 mod p=7∗84 mod 11=28672 mod11=6
    3. Decryption:
    PT=(c2∗(cp−1−d1)) mod p=(7∗511−1−3) mod 11=18 mod 11=7
    Example 2:
    let Plaintext M = 6
    e1=5d=2Randomno′r′=4
    1. Key generation:
    P=7,e1=5 and d=2
    e2=ed1 mod p=52 mod 7=25 mod 7=4
    2. Encryption:
    c1c2Random no r =4=er1 mod p=54mod7=625mod7=2=Pt∗er2 mod p=6∗44mod7=1536mod7=3
    3. Decryption:
    PT=(c2∗(cp−1−d1)) mod p=(3∗27−1−2) mod 7=48 mod 7=6
